Soós, L.: Anatomy and systematic position of Campylaea coerulans

CAMPYLAEA COERULANS. 41 same type as the Campylaeae. The chief characteristics of the genitalia of the Campylueae, as is well known, is seen from the spermatheca, the mucus glands, and the dart. Fig. 2. shows the whole reproductive system of C. coerulcim, but here I only discuss those parts which have a systematical importance. The most peculiar and permanent characteristic of the reproductive system of the Camjiylaeae is that it possesses either two simple or at Fig. Reproductive system of //. cocrulans. /'») = albumen gland, hm hermaphrodite gland, hv = hermaphrodite duct. pv — oviduct, or = prostate, kj = vas deferens, nym = mucus glands, p = penis, o - tlagellum, vi —- ]>enis retractor muscle, ot — spermatheca, f — diverticulum, i)nj =. generati\ e orifice, f = sacklike appendix of the spermatheca duct, ny = dart. the end forklike ramified mucus glands. C. coeiulans has also two very strongly developed, not ramified, cylindrical mucus glands, the ends of which are curled. These are at least as long as the oviduct, though frequently longer. The dart sack is to be found between the two mucus glands and opens into the vagina under the place of union of the ovisperm duct and of the spermatheca duct. The dart is spearheaded and thickened in the whole length of its middle part, thinned at the edges, i. e. double-bladed. All the Cam/ t/lacur have such doublebladed darts.
