238 MELANIID.E. 



This locality requires confirmation. I believe it to be al- 

 together distinct from Mel. nicobarica, but place it here tempo- 

 rarily until the exact locality is authenticated. It is of a light 

 green colour, obscurely spotted with brown below the suture ; 

 whorls much more convexly rounded, columella being corre- 

 spondingly twisted back ; the apical whorls are less numerous 

 and less attenuate, spiral striation less regularly and deeply 

 incised, altogether or almost obsolete on the upper portions of 

 the last few whorls ; under a lens the first few are minutely 

 decussated in the interstices. It appears also to be closely 

 allied to a form found by Baron v. Bichthofen, which I have 

 recorded as M. cerea, Bv. var. 



var. perstriatula, uov. 



10 Andamans [?] ; ex c. Dr. F. Stoliczka. 



The last two whorls are throughout regularly and evenly, 

 finely spirally striated. 



31. Melania [Striatella] crebra. 



Melania crebra, Reeve, Con. Icon., 1860, jig. 162, Q-uimaras ; var. from 

 Nicolars, Brot, pi. 33, fig. 2, as of Sect. Tarebia. 



12 Preparis Island [Bay of Bengal] ; coll. Dr. F. Stoliczka, and J. Wood- 

 Mason, Esq. 



I think it possible M. Brot's pi. 27, fig. 1A may represent 

 one of these specimens. Dr. Stoliczka sent some specimens to 

 the dealer Landauer. Long. 35, diam. llf mil.

A smaller form, the largest long. 31J, diam. 10J, in shape 

 well represented by pi. 27, figs. 2 and 2 A, 1. c., the M. zengana, 

 Mor., from Zanzibar. Specimens are often curiously contorted, 

 like some species of Eulima and as well shown in the above 

 fig. 2A. The sculpture is much more prominently developed, 

 more uniform, otherwise not unlike that of fig. 1A, 1. c. 

 Brot's pi. 33, fig. 2, evidently represents one of this form, 

 although the sculpture of the last whorl is more conspicuous 

 than in my specimens. I consider this species as very closely 

 allied to M. tuberculata.
