GOXIOBASIS. ZOO 



Diameter, -30; length, -04 of an inch. 



Observations. — This is a rather small species, very nearly allied to 

 ^lelania (Goniohasis') Taitiana (nobis), from Claiborne, Alabama, but 

 differs in being rather more inflated, of a darker color, and pj^. ^g- 

 having three dark bauds iustead of four. The bands iu 

 Xcv:hcrryi are broad and dark, sometimes running into each 

 other, uhile the Taitiana has thinner ones of a lighter color. 

 In some specimens of the latter the bands are absent, but I 

 have seen no specimen of the former without bands. These give a 

 dark appearance to the shell, -which is well relieved by the yellow 

 margin under the sutures. I have great pleasure in naming it after 

 Dr. Newberry, the discoverer of it. — Lea.

Description. — Shell small, conically oblong, shining, eroded, green- 

 Fig, 496. ish-brown; spire of 2-3 rounded whorls, remaining; sutures 

 profound; aperture ovately-rounded, scarcely effused. 

 Habitat. — Columbia River. 



Longitude, one-half; latitude, nine-twentieths poll. 

 Observations. — The whoi'ls are very cylindrical, so as to 

 appear like a succession of bulbs. It is much like M. perfnsca, Anth. ; 

 but in that the whorls slope gently to the suture. A broken speci- 

 men shows that it often attains a considerable size. — Gould. 



This species is exactly similar iu outline to Mr. Lea's N'eto- 

 berryi, but none of the specimens before me, including Dr. 

 Gould's types, exhibit the slightest indications of bands, while 

 Mr. Lea declares his species to be always banded.
