230 MELANIIDA. 
var, pseudaculeus, nov. 
1 Iles Marianes ; ex c, A. Morelet, Esq. [labelled “ M. aculeus ].” 
This is certainly not the M. aculeus of Lea, in Brot or 
Hanley, Con. Misc., being much nearer the latter's fig. 32, 
1. c., “M. fimbriata, Thorpe, ms.,” of which, indeed, it might be 
a variety. The sutures are excavate, slightly swollen beneath, 
as in var. asptrans ; the spire is rather less lanceolately produced 
than in any of the preceding forms ; though adult, it is scarcely 
decollate ; coloration uniform brown; spiral striation very 
irregular on the lower whorls. 
Anfr. 11 to 12 ; long. 514, diam. 123 mil. 
12. Melania zelebori. 
Melania zelebori, Brot, Mat. Mélaniens, IIT, 1872, Nicobars, long. 37, diam. 
8 mil. 
The young sometimes show obscure, short brown dashes [or 
streaks] below the suture and more or less throughout the last 
whorl. 
10 Katchall, Great Nicobar, and Camorta ; coll. F. A. de Roepstorff, Esq, 
Long. 53, diam. 16 mil.; anfr. 4. 
var. Nana, nov. 
2 Great Nicobar ; coll. F. A. de Roepstorff, Esq. 
Strongly decollate, only 3 to 4 whorls remaining—long. 294, 
diam, 104 mil. 
var. Solidiuscula, nov. 
6 Andamans ; coll. F. A. de Roepstorff, Esq. 
A very distinct variety, slightly decollate, 6 whorls—long, 
37, diam. 114 mil.; constantly distinguished from all the preced- 
ing by its greater solidity and by the less convex whorls, espe- 
cially noticeable in the last one. 
13. Melania blatta. 
Melania blatta, Zea, P. Zool. 8. 1850, Philippines, 
1 Philippines ?; coll. Baron F. von Richthofen.
