the pillar, which, with his figure, indicate that he had a species of 

 Mitra in hand, from which his diagnosis was made. 



The present species seems entitled to a distinct group name. 



DAPHNELLA BARTSCHI, new species. 



Plate 19, figs. 4, 5. 



Shell small, slender, yellowish white with brown flames and 

 flecks, moderately convex whorls, distinct suture, and six whorls, 

 with a very minute brown nucleus of two whorls ; the whole surface 

 is delicately reticulated with subequal axial and spiral threads, the 

 spirals cut by the axial interspaces into minute nodules, the inter- 

 stices squarish ; the surface resulting is grating to the touch ; the aper- 

 ture is narrow, the canal hardly differentiated and not recurved. 

 Height of shell, 8.5; of last whorl, 6; diameter, 5 mm. Cat. No. 

 267341, U.S.N.M. 



Range.— Lower California and the Gulf of California; Dr. Paul 

 Bartsch. 



This is much smaller and with more delicate and even sculpture 

 than the related species D. casta Hinds, and D. clathrata Gabb, both 

 of which have much larger nuclei. D. ejfusa Carpenter from Neeah 

 Bay, Washington, was founded on a broken and worn unidentifi- 

 able specimen probably not even belonging to the genus Daphnella. 

 D. electra Dall is a still smaller and differently colored species, and 

 D. fuscoligata Dall has quite a different sculpture and may possibly 

 be a Glathromangilia. 



CYTHARELLA ACULEA, new species. 



Shell small, purple brown, banded with white, or varicolored; 

 nucleus of one and a half loosely coiled, smooth nuclear, and four 

 subsequent whorls ; axial sculpture of six, somewhat sigmoid rounded 

 ribs continuous up the spire, with excavated, much wider interspaces, 

 with fine axial striation, which slightly wrinkles the spirals; spiral 

 sculpture of numerous sharp, often paired grooves separated by 

 wider flattish interspaces which are faintly marked by the axial stria- 

 tion; aperture narrow, anal sulcus conspicuous, outer lip thickened, 

 smooth inside, pillar simple, canal hardly differentiated. Height of 

 shell, 6; of last whorl, 3.5; diameter, 2 mm. Cat. No. 73994, 

 U.S.N.M. 



Range. — San Diego, California, to Cape San Lucas. 



Though small, this is one of the most elegant of the West Coast 

 species. The name was suggested by Doctor Carpenter. Some speci- 

 mens are more slender than others, and the coloration is variable.
