while the columella-margin is regularly excurved. The inner lip is 

 continued across the body-whorl in the form of a thin, closely adhe- 

 rent callus deposit ; the columella-margin, in advance of the umbili- 

 cus, is distinctly thickened, but does not form a tooth, nor a distinct 

 angle. The umbilicus is moderately large and deep, showing part of 

 the whorls. 



Height of the largest specimen, 2*5'""; breadth, 4*5'"™; length of 

 aperture, i-?"""; breadth, 2'""'. 



Oft Cape Hatteras, station 2109, in 142 fathoms, sixteen specimens, 

 all dead, but fresh (No. 35,733). 



This species resembles Rotella striata D'Orb. It is a much more 

 depressed shell than he figures, and the spiral lines appear to be 

 much more numerous and finer, nor does his figures show any distinct 

 thickening of the columella-margin.

Additional specimens of this species have been taken at station 

 2074, in 1309 fathoms; station 2098, in 2221 fathoms; station 2094, 

 in 1022 fathoms, and mutilated arms from a fish stomach, from station 

 2099, in 2949 fathoms. 



Calliteuthis reversa Verriii. 



These Transactions, vol. v, p. 295, pi. 46, figs. 1-16, 1881. 



Additional specimens of this species were taken in 1883, at station 

 2034, in 1346 fathoms; station 2039, in 2369 fathoms; station 2041, 

 in 1608 fathoms (head only) ; station 2076, in 906 fathoms. 



The young specimen of this species, from station 2076, has one of 

 the tentacular arms preserved. These arms have been absent in all 

 the other specimens that I have examined, and seem to be very easily 

 detached. In this example the tentacular arm is long, very slender.
