var. infracostata. 
Melania infracostata, Mousson, Moll., Java, 1849, pl. 10, fig. 3. 
3 Java; coll. Baron F. von Richthofen. 
Unfortunately not adult. Two are the young of a form 
resembling that represented in Mousson’s Moll., Java, pl. 10, 
fig. 4 [as “ M. varicosa, Troschel”’],—the whorls having longi- 
tudinal, distant ribs, on one specimen; these are quite obsolete on 
the last whorl, which, however, has a few spiral strie below the 
suture ; the third specimen shows similar longitudinal ribbing 
on the upper whorls, but the last whorl is spirally decussately 
striated, exactly as in the above-quoted figure of Mousson, 
var. SubVaricosa, nov. 
14 Arakan and Pegu [?]; exc. Dr. F. Stoliczka. 
Long. 654, diam. 24 mil. 
Reeve’s fig, 10 A, “ M. corrugata, Lamarck, India, &ec.,” may, 
perhaps, represent this form, though it has the semi-nodulose 
sculpture a little more developed. M. Brot’s pl. 10, fig. la, 
is close, but doubtfully identical; unfortunately, as in man 
other instances, he does not record the exact locality. The 
present form is more decollate, the ribs are straighter, a trifle 
further apart and more developed. The only figure that well 
represents it is that of the Voy. Bonite, pl. 31, figs. 11-12, la 
“ Melania indienne” from the Ganges, = Melania varicosa, 
Troschel, in text, l.c., not M. indica, Soul., as stated by Brot, 
a name I cannot find in the Voy. Bonite. There seems to be a 
gradual transition to the UZ, episcopalis, Lea, which lives in the 
same neighbourhood. ° 
10 Near Sibsagar ; coll, S. E. Peal, Esq. 
With sculpture not unlike that of WU. infracostata, Mousson. 
Jt is, I think, the form figured by Brot, pl. 10, fig. le. 
10 Near Sibsagar, Namtsik River, and Samaguting ; coll. S. E. Peal, Esq.
