178 PROCKEDINGS OF THE MALACOLOGICAL SOCIETY. 



Var. scALAKis, Moller. 



" Porcupine" Expedition, 1869, Station 65. 



Yar. KUGULATA, Moller. 



"Porcupine" Expedition, 1870, Station 26. 



I am not clear if the locality for tlie last-named variety be really 

 correct. Pleurotoma brevirostris, Jeff. MS., seems to me only a form 

 of turricula, while F. delicata, Jeff. MS., seems synonymous with the 

 variety rugulata. 



Bela sp. ? 



Two specimens from the cruise of 1870, Station 17, deserve a note. 

 They are veiy small, turreted, and well keeled, and the sub-sutural 

 area is smooth, save for weak radiating lines of growth. The 

 sculpture of the rest of the shell consists in distant, well-marked, 

 longitudinals, and numerous close-set spirals. Mons. Dautzenberg 

 very kindly examined them, but was unable to identify them. I have 

 not described them, as there are only two dead shells, not in good 

 condition. 



Bela sp. 



A single specimen, apparently live, from the cruise of 1869, 

 Station 38, bearing the MS. name of pinguis, Jeff., is in the Museum 

 collection. It appears not to belong to the species described under 

 this name by Locard (Exped. Trav. Talisman, vol. i, p. 211), but is 

 a true Bela. I have been unable to satisfactorily identify the shell, 

 but the variation in these forms is great, and I have therefore left the 

 unique specimen unnamed. 



Pleurotomella (?) BULLioiDES, u.sp. PI. XVI, Figs. \, \a. 



Shell ovate fusiform, spire rather depressed. Colour white, with 

 a chestnut-brown protoconch. Whorls 6, somewhat convex, suture 

 well marked. Protoconch composed of four whorls, the first minutely 

 punctate, the second and third being decussated by arcuate riblets, 

 while the fourth whorl has this decussation on its lower half, but one 

 series of riblets has become obsolete on the upper half. The residue 

 of the shell is, in some specimens, marked by three or four incised 

 lines, the only other sculpture being the lines of growth, which are 

 sinuous and more noticeable just below the suture. The last whorl is 

 large and inflated ; the mouth ovate ; columella slightly curved ; lip 

 thin and arcuate, with a deep sinus at its upper margin. Long. 4, 

 lat. 2"8 mm. 



"Porcupine" Expedition, 1870, Station 17. 



Ten specimens ; the details of the protoconch are taken from 

 a 3'ounger shell than the type. 



Belonging to the group of T. Dalmasi, Daut. & Fischer, but 

 a smaller and more ovate shell, the spire not being so elevated. It is 

 the ohesa, Jeff. MS., which name has been used three times in the 

 Pleurotomidae. 



I have forms apparently belonging to several distinct species of 

 this group from the same dredging, but we know so little of their
