386 H. L. STAHNKE Sca, 1600 metres (5349 ft), June 19, 1967. Under rocks, isolated from the ground, and from the plants. 4 çf. No. 827, at the same locality, 1500 metres (4920 ft), June 20, 1967. Collected at night by lamplight near the Salt Sea (about 21* 30 m : 16°C; 24 h : 12°C, early morning 9°C). At the beginning a clear sky, still night with full moonlight, about mindnight a strong south wind. 2 çf. No. 830, South Gobi territory: Nojon mountains, an oasis near a branch of Muchor örege river, 65 km W, of the border post of Ovot Chuural, 1450 metres (4757 ft), June 21, 1967. Wide extensive sandy desert with Haloxijlon, Tamariscus and Nitraria, Camp in a wide, dry river bed near the camp was a spring and a small creek, a valley with luxurious green vegetation, otherwise the region is very desolate. Isolated from the ground and from the plants. 1 çf. No. 845, Bajanchongor Territory: Border post at Caganbulag in the mountains of the Cagan Bogd range, 1550 metres (5085 ft), June 24-25, 1967. West of the spring in a large, wide dry river bed, which extends up to the Chinese border. Tamariscus, Zygophyllum and a few Caragana in the valley; the mountains are very rocky and almost without plant growth. Under rocks, isolated from the ground and from the Tamariscus. 8 çf. No. 846, at the same locality, 1550 metres (5085 ft), June 24, 1967. Collected at night by lamplight (about 21 h 30': 22°, 24 h : 20°, early morning 10°). Stormy wind. 1 9No. 847, Bajanchongor territory: Cagan Bogd mountains, Tooroin bulag spring, 13 km east of the Caganbulag border post in the Cagan Bogd range mountains, 1500 metres (4920 ft), June 25-26, 1967. Old poplar, Tamariscus, Salix, etc. Valley with flowering plants (Draba, Juncus, etc.j. Under rocks. 2 çf. No. 868, Bajanchongor territory: Dzun mod oasis, about 100 km south of Schine zinst Somon, 1300 metres (4265 ft), June 29, 1967. Poplar forest, with a waterless spring, the environment consists of a wide, extensive, sand semi-desert with Haloxijlon, Caragana, and Ephedra as well as Zyophyllum, the rest Nitraria. Under rock. 1 çf. All specimens taken at the above sites belonged to one taxon, Mesobuthus eupens mongoliens (BIEULA). Some night collecting by lamplight was done. It is noteworthy that the scorpions were apparently active on nights of strong winds with temperatures ranging from 9 °C (48 °F) to 16 °C (60 °F). Since all scorpions fluoresce in ultra violet light it is unfortunate that the expeditions did not have the use of a portable blacklight. This technique has proven to be an extremely effective means of sampling the populations of these nocturnal animals. They may be found climbing the branches of the vegetation and crawling over the ground surface. Apparently there must be a fairly large population of this taxon present in the various areas sampled. This is the judgement of the writer when comparing the numbers taken by daylight rock rolling, etc. with nocturnal blacklight sampling. Also, the sparser, more cryptozoic taxa are generally not encountered during daylight collecting. It is highly possible that new species would have been revealed with the U.V. light technique. With portable equipment now available scorpions and other fluorescing arthropods, as well as some desert lizards, can be detected al a distance of ten to forty feet. As indicated previously, the KASZAB collection establishes a new range for this taxon which now is known to extend from 40° to 47° N and 93° to 108 °E. The type material was taken from Alashan Province, Mongolia, about 40° X 108°. The qualitative characteristics of the additional material did not vary significantly from those previously reported (STAHXKE 1967). The quantitative description has been enhanced as indicated in the following table: Out of 76 specimens (49 cf, 27 Ç) the lengths range from, 0 * 17-42 mm, •Q 18-49 mm. As indicated by the above table the mean çf length was 33 mm and
