"Stoliczka's the animal appears to be of a brick red colour, with a pointedly 

 ** truncate tail and remarkably developed nearly vertical horn above, — 20 sp. 

 " Darjiling, coll. Dr. F. Stoliczka and Col. G. B. Mainwaring." In the 

 MS. book of Drawings, Mr. Nevill has written in pencil, " This is not 

 Macro, luhrica ? is it Mainwaring i or an ally ? It is a species of ^otulay 

 fide Stol."

[" Haughtoni. Andamans. Animal dark brown reddish at the pedi- 

 " cles. Mantle thick, greyish brown, freckled with white, body very rough,

 " cles whitish, basal edge pale greyish brown. Tail gland distinct sur-

Nevill's Handlist (1878), p. 46, places it in the Sub-genns Bhyssota^ 

 which I follow until an anatomical comparison shall be made with 

 R. ovum the type of the genus by Albers. Nevill says (1. c.) " The 

 ** animal very closely resembles that of N. ligulata,^ in a less degree iV^ 

 *' orohia the tail of which is less truncate &c., and some species of Ario- 

 ^^phanta^

Placed in Sec. B of Machrochlamys by Theobald — but it has no 

 shell lobes to the mantle. It is no doubt a close ally of E. vidua, Blanford, 

 described in J. A. S. B. 1880, p. 190, where he shows (taking suhopaca from 

 Ceylon as the type) how very similar it is in the odontophore and form of 

 the animal to that species. 



To the list of species of Euplecta given on page 193, should be added 



partita, Pfr. from Ceylon, and I would add also camura, Bs. Darjiling ; 



tugurium, Bs. has I find from a spirit specimen give me by Mr. Blanford, 



shell lobes to the mantle, and will therefore come into the sub-genus 



Macro chlaonys.
