178 THASIANELLA. 



P. PHASIANELLA C. B. Ad., 1852. Unfigured. 



"Shell ovate-conoid ; color various, mostly red or brown, some- 

 times uniform, frequently in dark flammules on a light ground, 

 sometimes with spiral darker stripes or series of spots; surface covered 

 with spiral striae; apex subacute; spire conoid, with the outlines 

 moderately curvelinear; whorls 5, convex, with a distinct suture; 

 aperture broad ovate, subeffuse; labrum thin; umbilicus very small. 

 -Mean divergence about 64; Alt. '16, diam. "11 in. Operculum 

 calcareous, very thick and solid." (Adams'). Panama. 



"In the calcareous sand we collected about 112 specimens in 

 various stages of growth'' (Adams). 



This species, the Turbo (?) phasianella of Adams, is said by 

 Carpenter to be the same as his P. (P. perforata var. ?) striulata. 

 I have seen neither. The description of the latter here follows: 



P. STRIULATA Carpenter, 1857. Unfigured. 



Shell similar to P. perforata, but lacking colored lines ; punctate 

 and spotted with rufous ; spiral stria? below, and in the umbilicus, 

 occasionally upon the spire. Alt. *09, diam. '07 in. 



Massatlan. 



Only two specimens found. One is very slejider, the other of the 

 ordinary form. There is no trace of the minutely wrinkled surface 

 [of P. perforata']. ( Carpenter).

P. MINIMA Phil. Vol. ix, PL 46, fig. 24. 



Ovate globose, thin, bluish black, smooth, slightly striate on last 

 portion, umbilicate; spire short, very obtuse; whorls 3, not convex, 

 last large; aperture oval, lip thin. Alt. 1*5 mill. 



Coast of Peru. 



Littorina umbilicata d'Orb., preoc. in Phasianella, is a synonym. 



Has been considered a Littorina, but the operculum is that of 

 Phasianella. 



I do not know that this and the following species belong to 

 Eucosmia. They resemble that group in the minute size, umbilicate 

 base and depressed form. 



P. BREVIS d'Orb., 1853. PI. 40, figs. 8, 9. 



Shell short, umbilicate, thin, smooth, white, variously flammulate 

 or irregularly maculate with blackish or red; spire very short, 

 obtuse; whorls 4, convex; aperture nearly round. Alt. I] mill.
