TORNATINA. 185 



larger. Fig. 24, of plate 22, represents B. obstricta Gould, which 

 seems to have no distinctive characters. 



T. CANDEI Orbigny. PI. 22, figs. 21, 22 ; pi. 50, figs. 27, 28, 29. 



Shell small, cylindrical, tapering below, milk-white, rather solid 

 but thin ; spire conical, terraced, the apex large and projecting. 

 Surface shining, smooth, except for faint growth-lines; whorls of 

 spire concave or channelled above. Aperture long and narrow ; 

 uter lip strongly arched forward, retracted at base ; columella 

 short, concave, with a moderately strong fold. 



Alt. 2-6, diam. 1-3 mill. 



Alt. 3, diam. 1-4 mill. 



Alt. 4, diam, 1-8 mill.

This species is constantly much smaller than T. canaliculata, with 

 larger, apex and more strongly curved outer lip. The spire varies 

 in height, being often somewhat scalar. Morch sees this species .in 

 Bulla pusilla Pfr., but the description of that form is hardly suffi- 

 cient for positive identification. 



T. PUSILLA Pfeiffer. 



Shell oblong, solid, shining white ; spire short, the apex mamil- 

 late; whorls 2, the last four times as long as the spire; columella 

 uniplicate at base ; outer lip arcuate in the middle ; aperture nar- 

 rowed above. Alt. 2, diam. \ lines (Pfr.~).

Probably identical with T. candei Orb. The T. pusilla of A. Ad. 

 (Thes. p. 568) seems to be something different. It is said to have a 

 rather wide umbilical fissure. 



T. LIRATISPIRA Smith. Unfigured. 



Shell cylindrical, a little wider above than at base, white, shining, 

 striated with curved growth-lines. Whorls 5, acutely margined 

 above, the first tubercular ; spire very short, turrited ; suture widely 

 channelled, divided by a hair-like thread in the middle ; aperture
