 Murex asperrimus Lam., Orbigny, Moll. Cuba, II. p. 158, 1853. 

 Murex pomiformis (Martini) Auctorurn. 

 ? Murex imperialis Tryon, ex parte. 



Habitat. Station 152, Flannegan Passage, in 27 fms., sand, temperature 

 78° F., one very young specimen, which I have figured. 



This species extends its range from the warm water off the coast of North 

 Carolina to Florida, the mainland round to Venezuela, etc., and the Antilles. 

 One of the brightest-colored specimens I have seen came from near Beaufort, 

 N. C. The colors are variable, and I suspect the Murex imperialis from the 

 island of Margarita, West Indies (if not an error for Margarita in the Gulf of 

 California), referred to by Mr. Tryon, is merely a very large, pale, bright- 

 mouthed M. pomum. The typical color of the mouth is pale salmon-color 

 picked out with dark brown, but in some specimens the brown becomes a 

 tolerably lively yellow, and the salmon-color a pale pink,, while in still others 

 the mouth is white, especially at inter-varical periods. The number of varices 

 is usually three, but this is not invariable; there may be four, or the number 

 may be irregular. The young shell sometimes looks like a little stumpy Fusus, 

 of a vivid pink. Varices are inconspicuous in the early whorls, which are 

 reticulated, while the nucleus is deep pink, or brown, smooth, small, and about 

 two-whorled. The epidermis of the young shell is quite hispid. 



Phyllonotus interserratus Sowerby. 



Murex interserratus Sowerby, Tlies. Conch. Murex, p. 39, no. 180, fig. 204, 1879. 

 Murex Pazi Sby., op. cit., fig. 208, not of Crosse. 



Habitat. Station 273, off Barbados, in 103 fms., coral; and Station 156, off 

 Montserrat, in 88 fms., sand, bottom temperatures 60° to 69° F. 



This is a very neat and pretty little species, which combines characters re- 

 minding one of Ocinebra, Paziella, Trophon, and Phyllcmotus. No habitat 

 was given for it by the describer, and it is now determined as Antillean for 

 the first time. 



Phyllonotus Pazi Crosse.

Habitat. Station 20, off Bahia Honda, Cuba, in 220 fms., bottom tempera- 

 ture 62° F. Also at U. S. Fish Commission Station 2655, on the Little 

 Bahama Bank, in 338 fins., sand, temperature 47°. 5 F. 



This is a remarkable little shell, which takes a long step toward uniting
