300 REPORT ON ALBATROSS MOLLUSCA BALL. 



sulcus is a row of larger and more prominent nodulations, the number 

 on each whorl being- the same as on the band ; there are also a few 

 transverse, sometimes sharp but generally obscure, ridges crossing the 

 whorls; spiral sculpture of fine obscure lines, often obsolete, but pretty 

 evenly distributed over the surface; aperture (broken) narrow, outer 

 lip simple; pillar simple, without any marginal keel; canal narrow, not 

 exhibiting any fasciole; base attenuated in front, gently rounded to the 

 periphery. Maximum longitude of shell, 18.5; maximum latitude, 4""". 



Hab. — U. S. Fish Commission Station 2750, off St. Bartholomew, 

 West Indies, in 496 fathoms, fine gray sand; bottom temperature 44°.4 F. 



The first three apical turns of this shell are smooth, then the sculpture 

 above described begins. The soft parts were not obtained. It resembles 

 the shell described in the Blake Eeport under the name of benthalis and 

 is doubtless a variety of it, in which the longitudinal sculpture has be- 

 come faiut and the nodulations intensified. 



Family CONID.E. 

 Genus CONUS Liune\ 

 Conils Cleryi Reeve. 



This species was collected at Station 2762, east from Rio Janeiro, in 

 59 fathoms, living; and at Station 2765, off the Rio de la Plata, in lati- 

 tude 36° 43', in 10£ fathoms, sflnd; temperature 59°. 1 F. 



The examination of these specimens leads me to believe that my sug- 

 gestion in the Blake Report that C. Villepiniij F. & B., might be iden- 

 tical with C. Cleryi, is not likely to prove correct. They seem much 

 more distinct than the figures of the species would indicate. 



Family PLEUROTOMIDJS. 



Genus PLEUROTOMA Lamarck. 



Subgenus LEUCOSYRINX Dall. 



Leucosyrinx Goodei sp. nov. 



Plate vi, Fig 1. 



Shell large, thin, white, with a tinge of pale orange in the throat and 

 on the pillar; whorls eight (or more), nucleus wanting in the speci- 

 mens; surface generally slightly eroded, glistening when perfect; spiral 

 sculpture below the periphery of narrow shallow grooves separating 

 wider, half obsolete threads; at the periphery is an obtuse carina which 

 is sharper ou the early whorls ; behind this is a wide shallow sulcus, 

 behind whicli the whorl rounds to the distinct but unchannelled suture; 

 on the upper or posterior part of the whorl the fine spirals are percep- 

 tible but fainter than in front of the periphery ; transverse sculpture 

 only of incremental lines ; aperture elongated moderately wide ; anal
