a long epiphallus, and a very long and tapering flagellum. 

 The sheatli of the penis is bent into S-foini. kSpermatheca 

 a globose sac on a long stalk; it contained oidy the capsule 

 of a spermatophoie, all trace of the rest had disappeared. 



The radula was very perfect. It is very ciiaracteristic, 

 not exactly like any other I have seen. The central and 

 admedian teeth rather more elongate than usual, the latter 

 with a single basal cusp on the outer side ; the eleventh 

 tootli rises higher and the plate is much narrower at the 

 tifteenth ; the teeth are long, narrow, and nearly evenly 

 bicuspid, becoming very small and still narrower on the 

 margin. 



Formula : 56 . 10 . 1 . 10 . 56, or 66 . 1 . m. 



Jaw with a central projection. 



Will be figured in the next part.

Shell small, flattened, of few whorls, the apical close-wound 

 and rapidly increasing. 



Animal (extremity of foot not seen) has a broad, short, 

 right shell-lobe and a small triangular left shell-lobe. Gene-

^' At once distinguished from all South-African congeners 

 yet known to us by its small size. The anatomical details of 

 this si)ecies, as well as russofnhjens, are at present unknown, 

 but the shells of both seem distinct enough to warrant 

 description." 



Two specimens were received through Mr. Ponsonby ; they 

 are not so large as the type shell in the Natural History 

 Museum. The animal was not in a good state, so very little
