Generative organs as in the genus. The muscular coDCum (crp) 

 is short, and so is the loop below it. In this specimen a spermato- 

 phore in process of formation was discovered (Plate XCVII. figs. 1 h, 

 1 (•) and is noticeable, in form quite unlike those of the Macro- 

 chlamidaj. It consists of a large elongate conoid mass set on one 

 side with minute spines at the base, these becoming in succession 

 larger above ; here and near where the vas deferens unites with 

 the penis is the thin capsule, also spined down one side, the spines 

 being bifid and arranged in sets of two together. This may be 

 compared with the figures of the spermatophore of Nlhjiria tranque- 

 hancn on Plate XCIV^. figs. 5-5 f, where, it maybe seen, the normal 

 position near the junction of the vas deferens is the same. 



The full breadth of the radula was not seen, the outermost teeth 

 having been lost.

The teeth are similar in shape to those of other species of the genus. 



This shell is not fully grown, but it is nearly so, as shown by the 

 advanced stage of development of the spermatophore. And this 

 opens up another line of inquiry. At what stage in their growth 

 do they unite in reproduction? I have had, therefore, some hesi- 

 tation in naming it. I referred it to Mr. Sykes, who has been 

 lately studying Ceylon shells ; he writes : — " I cannot quite name 

 this, it runs very near to several of the Evpleda group." It may 

 turn out to be the young of some well-known Ceylon species. I 

 trust Mr. CoUett will endeavour to procure a series of species of 

 Euplecta in all stages of growth. Mr. E. R. 8ykes has described 

 and figured one under the title E. coUetti * ; a close ally of this is 

 Eftplecta isahelUna, Pfr., fig. 7 of same plate. There is yet another, 

 E. scohinoides, described and figured, figs. 1, 2. All three species 

 are sharply-keeled forms. 



Among Ceylon shells the following species may be expected to 

 belong to this subgenus : gardneri, suhconotdea, {sahelliiia, emi- 

 Viana^cingaJensis, novella^ albizonata, &c. In Southern India: 

 frnvancorica, Tcoondaensis, and suhdecussnta. The animals of all these 

 and some other species require to be examined.
