Note by Nevill: "Animal large and very active, yellow, 

 here and there lightly mottled grey ; small lobe above 

 mucous gland, mucous gland indistinct." 



Ne\'ill was a conchologist, and had had no training in the study 

 of anatomical details ; but from association with Ferdinand Stoliczka 

 and others, he was beginning to recognize the value of the outward 

 form of the animal und the work that Stoliczka had initiated in 

 India, and I owe much myself to this same gifted naturalist. It 

 is quite apparent on what Nevill based his two sections. He was 

 aware, from the paper by Blanford, of the differences between Semper' s 

 types E. suhopaca and E. Lat/ardi, and he jilaced in Euplecta proper 

 the more globose, convex-sided shells, proposing the new section for 

 the decidedly keeled ones, many of which partake in this respect 

 of the character of the genus Sitala. Further anatomical study 

 of Ceylon shells will solve the question as to the true position of 

 E. Zayardi, and what species are allied to it. 



In one very small Ceylon shell sent me by Mr. Syl<es, collected 

 by Mr. H. B. Preston, the dried-iip animal remained ; and after 

 soaking it well, I was able to make out the form of the foot, and 

 to extract the radula in a complete state, with not a tooth lost. This 

 radula agrees in every way with Semper' s figure of that of the tyi^ical 

 species E. suhopaca} 



The costulation of the shell is so like that of several of the Ceylon 

 keeled forms that there is every probability of many others belonging 

 to the same generic stock ; and I much wish to obtain a good 

 number of species to examine, and so carry on the work Professor 

 Semper so well began. I am glad to say there is every hope of 

 doing this, since Mr. Collett has written to say he is now collecting 

 the animals of all he can find and preserving them in spirits.
