A REVIEW OP THE VOLUTIDAE 



Dall Indicated the confused state 

 of the synonomy and thought It might be 

 best to discard the name maiellantca. In 

 this case, Rochebrune's name of bracata is 

 probably the earliest which could be used 

 for the species. 



The ovicapsule with the nepionic 

 shell has been figured by Dall in the Proc. 

 of the United States National Museum, pi, 9, 

 figs. 5, 6, 1889.

 Museum; Huelmo, Chile, near, Puerto 

 Montt, about south latitude 40°, near 

 extreme low water. Coll. Dunker; Argen-

 latitude about 45), Argentina In 48 

 fathoms, sand; U.S.S. Albatross (young 

 shells) . 



Dall stated that he had not seen 

 the above species in the adult state, which, 

 by Strebel 's rather rude figures, would 

 seem to be very similar to a well preserved, 

 somewhat thin and inflated form of A . 

 maiellantca . The young specimens which 

 agree with Strebel 's figure, bear the num- 

 ber 96,177 in the U.S. Natural Museum. 



Adelomelon ornata (Lahille) I895 

 (Unflgured) 



Voluta fusiformis ornata Lahille, Rev. Mus, 

 de la Plata, 6, p. 299, (extras p,'9), 

 pi, 4, figs, 24-26, 1895; not pi, 5, 

 figs. 16, 17.

Alt. 105 mm. 



Hab. Coast of Argentina, near the La Plata 

 Estuary. 



Aside from the zig-zag vertical 

 streaks of brownish coloration, this spe- 

 cies has little in common with A. beckil. 



Nucleus large, blunt, irregularly 

 coiled; shell sblld, with strong spiral 

 sculpture; columella with two distinct 

 plaits behind the one which forms the edge 

 of the columella. 



Adelomelon paradoxa (Lahille]

Hab, Coast of del Sur, Argentina. 



Last whorl with variegated zig-zag 

 brown markings. According to Lahille, the 

 young shell is different from any of the 

 other species, that it cannot be properly 

 united with any other. The young shell at- 

 tains a length of 55 umi, and a diameter of 

 40 mm. It has three plaits, the two poste- 

 rior most prominent. The weight is slight- 

 ly more than one-half than that of A .
