is much less transverse. It is also devoid of the spots in the interior of transversa. 

 It is near to atra Richard and siibimhricata Philippi. (See Phil. Conch jlien, v. 3, pi. 5, 

 f. 2 and 3.) Aperture about one-fifth the length of the shell. 



Melania bullata. pi. 22, fig. 29. 



Testa striata, obtuso-conoidea, valde inflata, crassa, nigra ; spira curta, truncata ; suturis parum im- 

 pressis ; anfractibus convesis, striis transversis subdistantibus impressis ; apertura grandi, subovata, 

 superne angulata et incrassata ; intus albida ; labro acuto ; columella incurva tortaque. 



Shell striate, obtusely conoidal, very much inflated, thick and black; spire short, 

 truncate ; sutures somewhat impressed ; whorls convex, with rather distant transverse 

 impressed strise ; aperture very large, subovate, above angular and thickened, white 

 within ; outer lip sharpened ; columella incurved and twisted.

Eemarlcs. — Two specimens were submitted to me by Mr. Haines. One has but 

 two and a half whorls remaining, the other not quite four and a half. They are both 

 cut off square at the apex. Neither of them have any folds remaining on the lower 

 whorls. When the spire was perfect, very probably there were folds on the upper 

 whorls. This is a very remarkable species. It is most nearly allied to transversa 

 (nobis,) but differs in not having folds, in being much more inflated and shorter, and 

 in having a much larger aperture. The transverse strias are much less impressed, 

 and they are much more distant. The aperture is less than half the length of the 

 shell. 



Goniobasis Eomje. pi. 23, fig. 30. 



Testa subearinata, conoidea, siibcrassa, tenebroso-cornea, evittata; spira subelevata, aliquanto obtuse elevata ; 

 suturis impressis; anfractibus septenis, planulatis, superne carinatis ; apertura grandiuscula, ovata, 

 intus albida; labro acuto, subsinuoso; columella tenui et contorta. 



Shell slightly carinate, conical, rather thick, dark horn color, without bands ; spire 

 somewhat elevated, sometimes obtuse ; sutures impressed ; whorls seven, flattened^ 

 carinate above ; aperture rather large, ovate, whitish within ; outer lip acute, some- 

 what sinuous ; columella thin and twisted.
