104 BULLETIN OF THE 



these are slightly oblique, and extend from the anterior margin of the anal fas- 

 ciole to the suture in front; whorls a little irregular in form; suture strongly 

 appressed; sculpture, as usual, less strong, but still perfectly distinct, on the 

 fasciole; the notch rather deep, semicircular behind. Aperture longer than 

 half the shell, moderately narrow, with the canal well defined and somewhat 

 curved to the right ; outer lip thickened within, slightly dentate at the margin 

 from the spiral sculpture ; a slight callus on the body and pillar, well inside 

 the aperture ; pillar nearly straight. Lon. of shell, 11.5; of last whorl, 9.0; 

 of aperture, 7.0 ; lat. of shell, 5.2 ; of aperture, 2.0 mrn. 



Habitat. Station 272, in 76 fms., off Barbados, hard bottom, coarse sand 

 and shell ; temperature of bottom water, 65°.0 F. 



This is an extremely pretty little shell, not properly of the deep-sea fauna, 

 perhaps, but apparently undescribed and (except for its stronger sculpture) 

 bearing a curious resemblance in miniature to Pleurotomella Emerto lii. 



Daphnella pompholyx n. s. 



Plate XXXVI. Fig. 4. 



Shell thin, inflated, polished, with a brown Sinusigera nucleus of three 

 whorls, and five subsequent whorls ; color yellowish white, with faint axially 

 directed streaks and blotches of olive brown, and articulating dots of the same 

 in the region of the canal ; spiral sculpture of faint close-set scratches or half- 

 obsolete minute threads more or less visible over the whole surface, and on 

 the last whorl in front of the fasciole about twenty-five channelled sharply 

 cut grooves separated by considerably wider flat interspaces ; the grooves are 

 nearer together on the canal, and the interspaces there become rounded, almost 

 thread-like ; transverse sculpture of, on the fasciole, numerous little-elevated 

 arched regularly-spaced ripples, with slightly wider interspaces ; these fade 

 away in front of the fasciole, or appear only as irregularities of growth which 

 punctuate the channels but are obsolete on the interspaces ; whorls rounded, 

 fasciole only slightly excavated, the posterior edge appressed at the suture ; 

 aperture large, outer lip rather straight in the middle, contracted suddenly to 

 form the canal, the edge sharp, the sculpture transvisible, the notch shallow 

 and its corners rounded off ; columella straight, simple, rather long, canal 

 distinct, not recurved ; the periphery of the last whorl a little flattened. Max. 

 lon. of shell, 12.5 ; of last whorl, 9.2 ; max. lat. of shell, 6.0 mm. 



Habitat. Station 273, near Barbados, in 103 fms., coral and shells, bottom 

 temperature 59°. 5 F. Station 299, near Barbados, in 140 fins., coral, temper- 

 ature 56°. 5 F. 



This shell has somewhat the same outline as I), reticulosa, but its sculpture 

 is entirely different ; it is larger, thinner, and has a different nucleus. The 

 dry animal in one specimen is destitute of an operculum.
