slender duct arranged frequently like coils of vermicelli. Sperma- 

 thecee as usual, one pair opening in 4/5 with or without glands ; 

 duct about equal in length to ampulla, short, stout, gourd-like in 

 outline (see fig. 15). The most striking peculiarity, however, is 

 the presence of a pair of glands (possibly aborted salivaries)

 like the two ends of a clergyman's bands or cravat. Hence the 

 specific name focale. The nephridia were not studied. 



It will be observed that the position of the girdle and sperm- 

 funnel, the point of origin of the dorsal vessel, and the peculiar 

 glands, differentiate it from B. appendiculata and B.fallax, while 

 the spermatheca? show it to be unlike B. parva — a species not yet 

 found in Britain. The brain, salivaries, spermathecae, and origin
