tata, Cpr. It is much larger and differently colored from angu- 

 lata, and the carina in that species is near the middle of the 

 whorl, the grooves are much stronger and the ribs reach the 

 suture, which is not as deep as in the aleutica. In crebricostata 

 the whorls are not so much angulated, the ribs pass from the 

 suture to the lower end of the whorl, and the mouth is narrower 

 and longer. The shell is also much more slender and smaller. 

 These comparisons have been made with the typical specimens. 



Mangelia funebrale, n. s. 



Shell reddish black, small, slender, acuminate ; whorls seven 

 or eight, rather rounded ; aperture elongate, narrow ; canal 

 short, slightly recurved. Inner lip and columella smooth ; sinus 

 almost imperceptible. Sculpture consisting of fine rounded 

 grooves about fifteen in number on the last whorl, rather stronger 

 on the convexity of the whorls, separated by evenly rounded 

 ridges about twice as broad as the grooves. These are crossed 

 by rounded, regular, longitudinal ribs, about twelve in the last 

 whorl obsolete on the anterior end of the whorl ; suture impressed, 

 not deep.

After a careful comparison with types I find no species at all 

 resembling this from the Upper Californian coast. I refer it to 

 Mangelia with some doubt, as that and allied genera stand sadly 

 in need of careful revision and definition. 



Daphnella fuscoligata, n. s. 



ClatJmrella ? indet. Dall, MSS., 1866. 



Shell fusiform, slender, solid, of four or five whorls ; spire 

 half as long as the shell, aperture the same ; the latter narrow, 

 with no perceptible sinus, and a short open canal ; columella and 

 outer lip smooth. Sculpture consisting of strong, revolving, ele- 

 vated lines, six on the last whorl, crossed by strong, regular, 

 longitudinal costEe of about the same size, twelve on the last 

 whorl. These ridges are remarkably uniform, and their inter- 

 sections produce a very conspicuously regular reticulation. The 

 longitudinal ridges are, perhaps, a little thicker on the convexity 

 of the whorls than above and below. General coloration white, 

 with a reddish brown band between the suture and the first re- 

 volving ridge, another between and including the third and fourth 

 ridges, the other revolving ridges being dotted with brown be-
