238 MELANIIDE. 
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. Itis 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. Richthofen, which I have 
recorded as WU. crea, Rv. var. 
var. perstriatula, nov. 
10 Andamans [?]; exc. Dr. F. Stoliczka. 
The last two whorls are throughout regularly and evenly, 
finely spirally striated.

Melania crebra, Reeve, Con. Icon., 1860, fig. 162, Guimaras; var. from 
Nicobars, Brot, pl. 83, 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 pl. 27, fig. 1A may represent 
one of these specimens. Dr. Stoliczka sent some specimens to 
the dealer Landauer. Long. 35, diam. 11$ mil.

A smaller form, the largest—long. 31}, diam. 104, in shape 
well represented by pl. 27, figs. 2 and 2A,1.c., the M. zengana, 
Mor., from Zanzibar. Specimens are often curiously contorted, 
like some species of Hulima 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, Lc. 
Brot’s pl. 38, 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.
