think, clear, that Fenissac considered the first described species, V. Taunai/si 

 as the type of the genus, (Comp. Moll. terr. and fluv., II, pp. 96^, 96^, 

 and explic. des pi. No. 13, pi. 8 c). Ferussac's characteristic of the genus 

 places the pulmonary opening at a distance of two- fifths of the length of the 

 body from the anterior end, and on the lower right side of the mantle ; the 

 female sexual opening is said to be on the same side, about the middle ; the 

 position of the anus is not mentioned. Blainville's account of the anatomy 

 is not clear and partly contradictory to Ferussac's statement. Some of the 

 figures appear to leave no doubt that the position of the female sexual 

 organ is the same as that indicated by Ferussac, in others (fig. I and III,) 

 its situation is too much backward. The anus appears to be situa,ted accord- 

 ing to figure I near the sexual opening, but again it is said to terminate 

 with the anus at the posterior upper end of the foot. In the figures II and 

 III (1. cit.), which give an insight into the whole anatomy of the animal, 

 the true termination of the intestines is nowhere given. All this is very 

 unsatisfactory. 



Eydoux and Souleyet in their figure of Yagimdus Tourannensis also 

 record a small opening at the posterior lower right end of the mantle. I 

 can scarcely believe that this is correct ; it is probably only a fault of the 

 artist who thought that an opening must exist there, because it is clearl}^ seen 

 in the other species on the same plate, Vag. Luzonicus, which is a Vero- 

 nicella. 



My reason for doubting the correctness of Eydoux and Souleyet's figure 

 is the very careful examination of the Penang species, which, as already 

 mentioned, is closely allied to V. Tourannensis , if not really identical 

 with it. 



The Penang species has the following generic characters, as compared 

 with those of Veronicella. 



The sexes are distinct, the male opening is under the right peduncle, the 

 female sexual opening lies, together with the anus and the pulmonary orifice, 

 at the lower right side of the mantle, about two-fifths of the length of the 

 body distant from the front. The sexual opening is nearest to the edge of 

 the foot, then comes the anal and then the respiratory one ; they are only 

 separated by thin laminae from each other. There is no jaw present, the 

 manducatory organ consisting of a simple muscular tube, much as in Strep- 

 taxis or Testaoella ; the radula is short, composed of simple pointed teeth 

 which are absolutely identical with those of the two last mentioned genera. 

 There is no opening whatsoever at the posterior end of the foot or mantle ; 

 the pointed end of the intestinal organs is only attached by a bundle of 

 muscles to the terminal inner surface of the mantle. 



On p. 96r of Ferussac's Moll. ter. and fiuv., Blainville says that the upper
