cies. The known hosts are diverse rodents, further hedgehogs and polecats. Under laboratory conditions, it develops in foxes and also in man (PETROTSCHENKO, 1958). Localization: small intestine. Postembrional development takes place in Tenebrionid and Blattid species. PETROTSCKENKO (1958) distinguishes three subspecies of M. monili formis (Bremser, 1811) Meyer,

1933, according to differences in body measurements, proboscis length, configuration of hooks, and number of hook rows and hooks per rows (

M.moniliformis monilifor mis Meyer, 1933; M. moniliformis siciliensis Petrotschenko, 1958; M. moniliformis aegyptlacus Petrotschenko, 1958). Of these, two -namely the nominate form and ssp

.siciliensis - , occur in Europe. On morphological characteristics, the specimens collected from the small intestine of the lesser mole rat most closely resemble the nominate form, M.moniliformis moniliformis Meyer,

1933 (MEYER., 1933; VAR CLEAVE, 1953; EABOS,1955; PETROTSCHENKO

, 1953), OUT their body length is comparable to that of M. moniliformis sici liensis Petrotschenko, 1958 (Table 1.). However, they cannot le assigned to that category, since the proboscis of ssp

.

siciliensis beax-3 14 rows of hooks, whereas my specimens exhibit merely 12 rows of hooks. To decide whether the small measurements are due to the great population density or actually represent features characteristic of a new subspecies, I endeavoured to obtain comparative material from small mammals of the same locality. Accordingly, I have examined 17 Moniliformis specimens found in the small intestine of 6 gophers (Citellus citellus L.) infected with Acanthocephalids (collected by MÉSZÁROS, 28 September

,1966, and MATSKÁSI et SZABÓ, 5 July,

1968). Their measurements (in mm) are as follows: Pive immature males: 12-to 22 Two immature females: 12-60 Pour mature males: 28-31 Six mature females: 87, 103, 111, 130, 185, 210.
