 sulculate, the two last rapidly increasing, the last lightly carinated, 

 oblique, descending, the sulculse of the base more distinct ; aperture

This species has been heretofore confounded with the smaller, 

 differently proportioned T. pumilio according to SulHotti. That 

 species (pumilio) is figured on pi. 40, fig. 35. I have included it 

 in Gibbula, doubtless in error, as it seems to be a Calliostoma. I have 

 not seen specimens. 



Calliostoma of uncertain position, or un figured. 



ZIZYPHINUS INDISTINCTUS (Wood) Reeve, Conch. Icon., f. 35. 

 See Cantharidus indistinctus, page 128. This shell I have not seen. 

 It has also been figured by Philippi, Conchyl. Cab., pi. 43, fig. 7. 



ZIZIPHINUS NEBULOSUS A. Adams. Shell conoidal, imperforate, 

 rufous-brown, variegated with white ; whorls nearly plane, orna- 

 mented with unequal granose cinguli, the last subangulate, base a 

 little convex, ornamented with subgranulose cinguli, articulated 

 with brown and white ; aperture subtetragonal ; columella white, 

 incurved, subtruncate at base; lip lirate within. (Ad. in P. Z. S. 

 1851, p. 168.)

ZIZIPHINUS ASPERULATUS A. Adams. Shell conical, imperforate, 

 whitish, ornamented with radiating purple spots ; whorls nearly 

 flat, carinated in the middle, ornamented with unequal cinguli, the 

 superior granulate, inferior nearly plane ; last whorl subangulate, 

 base plane, sculptured with flat ribs ; umbilical tract depressed, 

 covered by - a callous; aperture subrotund; columella straight,
