58 FUSING. 



Var. CLOSTER, Philippi. PL 36, fig. 132. 



Spire usually more drawn out ; sometimes uncolored beneath 

 the light olive epidermis. Length, 6 to T5 inches. 



IsL of Margarita, W- 1. 



I have a fine suite of this form connecting it very completely 

 with F. distans. 



Var. DUPETITHOUARSII, Kiener. PL 36, figs. 133, 134. 



Unicolored beneath the light olive epidermis ; spire more elate 

 than the type ; upper whorls more or less tuberculate, the tuber- 

 cles usually vanishing before the last whorl, although sometimes 

 continued and forming an angle upon it ; body usually well 

 rounded, showing no distinct shoulder, encircled throughout 

 with revolving ribs, no tubercles. 



Galapagos Isles ; W. Coast of Central America, N. to Acapulco. 



Kiener's figure of this form (fig. 133) represents a shell quite 

 similar to F. distans, and the collection of the Philad., Academy 

 contains a similar specimen ; ordinarily, however, the non-carinate 

 form obtains, and such is represented by the figures of Yalen- 

 ciennes and Reeve. Fusus Novde-Holtandise. Reeve, next de- 

 scribed, is certainly very closely allied to this species. 



F. SPECTRUM, Ad. and Reeve. PL 36, fig. 135. 



Shell slim, graceful, unicolored, white under a light brown 

 epidermis; spire whorls crossed by rounded ribs, which are 

 evanescent on the body, the latter having a sharp carina of com- 

 pressed tubercles, defining a shoulder. Length, 3 inches. 



Eastern Seas ; Japan. 



Var. NOV^E-HOLLANDUE, Reeve. PL 31, fig. 137 ; pi. 33, fig. 108. 

 Ribs continued over the body-whorl, obliterating the carina 



and shoulder. Length, 4 to 6 inches. 



Australia. 



F. multicarinatus, (non Lam., fig. 108) = F. JReeveanus, Phil,, 

 appears to be the same species. 



Notwithstanding its slimmer form it is very doubtful whether 

 this should be considered specifically distinct from the last 

 species. Fusus albus, Philippi is, according to the description, 

 a synonym of the variety.
