NO. 2295. NEW NORTH PACIFIC MOLLVSKS—DALL. 355 



of a small glassy subglobular slightly depressed nucleus; the suture 

 constricted but hardly appressed; spiral sculpture of fine uniform 

 striae with slightly wider interspaces, covering the whole shell; 

 aperture subovate, the outer lip thin, the body with a continuous coat 

 of enamel, the pillar arcuate; the umbilicus naticoid, narrow, twisted, 

 with an internal spiral ridge. Operculum ? Height of shell, 3 ; of last 

 whorl 2; diameter, 2 mm. U. S. Nat. Mus. Cat. No. 250230. 



Type-locality. — Off San Diego, California, outside the kelp line, in 

 16 to 20 fathoms, C. W. Gripp. 



The true place of the shell is in doubt. It most recalls a minute 

 littoriniiorm Eunaticina. 



VELUTINA GRANULATA, new species. 



Shell small, white, naticoid, covered with a thin yellowish dehiscent 

 periostracum, with a min\ite smooth nuclear and three subsequent 

 rounded rapidly expanding whorls; suture distinct, not appressed; 

 sculpture of quite evident but not elevated incremental lines and 

 very minute granulation over the whole surface; aperture ovate, 

 produced, simple; axis imperforate, twisted, the pillar lip hardly 

 thickened, slightly reflected. Height, 5; diameter, 4.5 mm. U. S. 

 Nat. Mus. Cat. No. 214455. 



Type-locality.- — -U. S. Fish Commission station 4441, off Point 

 Pinos, Monterey Bay, California, in 35 fathoms, sand. 



This species seems to bridge the gap between species like V. conica 

 Dall and the more encoiled Lamellarias as far as the shell is concerned. 



TORELLIA AMMONIA, new species. 



Shell large, cartilaginous or leathery, depressed, brown, of some- 

 what more than two whorls; the nucleus, comprising a little more 

 than one whorl, has spiral elevated lamellae with wider interspaces, 

 much as in the larval envelopes of Lamellaria, but on a larger scale; 

 the remainder of the shell has close-set axial fringed lamellae; the 

 suture is deep, the aperture entire, wider than high; the umbilicus 

 is pervious, moderately wide, as in Planorhis trivolvis, the animal is 

 distinctly Velutinoid, and carries no operculum. Height of dry 

 shell, 12; greatest diameter, 24 mm. U. S. Nat. Mus. Cat. No. 

 111367. 



Type-locality. — Southwest of Sannakh Islands, Alaska, at U. S. 

 Fish Commission station 3213, in 41 fathoms, sandy bottom. 



TORELLIA VALLONIA. new species. 



Shell small, the earlier part of it with a calcareous lining under a 

 leathery periostracum, the latter part entirely flexible; the general 

 form and aspect that of Vallonia gracilicosta on a larger and some- 

 what less depressed scale; the color is yellowish brown, with about 

 four whorls, the nucleus missing, the rest of the shell with elevated
