Conus proteus humerosus n. subsp. Plate XXI, flg. 4. 



Some specimens in the lot of proteus have fewer spots, as noted 

 by Gabb. In the one figured there are 6 spiral rows of spots on 

 narrower continuous bands. In another there seem to be 7 such 

 spotted bands, but the color is nearly obliterated. Both of these 

 shells are very broad-shouldered; otherwise they agree with C. 

 proteus. 



Length 65 (apical whorls lost), diam. 45 mm. (Type, no. 2548). 



Length 64, diam. 40.5 mm. 



This cone agrees with C. williamgabhi Maury in general shape 

 and dimensions, but the whorls of the spire are concave, without 

 spiral threads, and there are no spirals in the lower part of the shell.

This is apparently synonymous with C. cercadensis Maurj'.

 Comus gracilissimus Guppy, Maury, Bull. Amer. Pal. v, p. 40. 



In Bowden specimens of Conus qracilissimus the spiral cords are 



flattened and slightly wider than their intervals. In C. gabbi they 



are much narrower than the intervals and not at all flattened. This 



is not a matter of age. We have not seen the Bowden species from 



Santo Domingo. ^

While this species doubtless was the ancestral form of the recent 

 C. reticulata (L.), it differs in several minor characters. The shell 

 is thinner and the whorls of the spire are slightly more convex, giv- 

 ing the spire a less attenuated appearance; the reticulations are
