TURBONILLA (PYRGOLAMPROS) GOULDI, new species. 

 Plate 6, figs. 1, la. 



Shell slender, light brown. Nucleai' whorls small, two, depressed, 

 helicoid, having their axis almost at right angles to that of the suc- 

 ceeding turns, in the first of which they are slightly immersed. Post- 

 nuclear whorls increasing regulai'ly in size, marked by low, rounded, 

 feebly developed axial ribs, of which there are 24 upon the second 

 to fourth, 20 upon the fifth to eighth, 22 upon the ninth and 

 penultimate turn. Intercostal spaces narrow and shallow. Sutures 

 moderately impressed. Periphery of the last whorl well rounded, 

 somewhat inflated. Base short, inflated. Entire surface of spire 

 and base covered by numerous fine, closely spaced, wavy spiral stria- 

 tions. Aperture oval; posterior angle acute; outer lip thick within, 

 thin at edge ; columella moderately long, sinuous, and slightly reflected. 



The above description is based on two cotypes, one (Cat. no. 163256a 

 U.S.N.M.) from San Pedro, California, has furnished the description 

 of the nucleus and early whorls, the other (Cat. no. 159990, U.S.N.M.) 

 also from San Pedro, consisting of the last seven whorls, has fur- 

 nished the adult characters. The young specimen has 9 post-nuclear 

 whorls and measures: Length, 5.8 mm., diameter 2 mm. The adult 

 specimen measures: Length 6.1 mm., diameter 2 mm. 



Cat. no. 162561, U.S.N.M., contains a fragment collected by Henry 

 Hemphill at Pacific Beach. Cat. no. 163256, U.S.N.M., nine speci- 

 mens from San Pedro, collected by Mrs. Oldroyd. Cat. no. 163258, 

 U.S.N.]M., one specimen, dredged by the U. S. Bureau of Fisheries 

 at station 2900, in 13 fathoms, oft' Santa Rosa Island. Another

Shell similar to T. (P.) cAocoZate Carpenter, but much broader, with 

 the close spiral striation a little more pronounced than in that species, 

 covered by a golden-yellow epidermis. Nuclear whorls decollated in 

 all our s])ecimens. Post-nuclear whorls moderately rounded, but 

 little C(Hitracted at base and but verv slightlv shouldered at the sum-
