siders to equal albolineata), and V. arena. The latter has not heen found on 

 the western coast, but the specimens of varia and West Indian albolineata are 

 very similar to one another. 



Volvarina subtriplicata Orbignt. 



Marginella subtriplicata Orbigny, Moll. Cuba, II. p. 99, 1845. 



Marginella triplicata Orbigny, Moll. Cuba, pi. xx. figs. 30-32, 1842, not of Gaskoin. 

 Marginella lactea Reeve, Conch. Icon., pi. xvii. fig. 81, and pi. xxiv. fig. 135; not of 

 Kiener. 



Habitat. Station 9, seven miles S. by W. from Sand Key, in 111 fms., 

 bottom temperature 55°. 5 F. 



The fourth plait is often quite perceptible, and I confess to some doubt of 

 the validity of this species. I have not, however, enough authentically named 

 material to decide on its relations with confidence. It seems to be rare. 



Volvarina pallida Donovan. 



Bulla pallida Donovan (not Linne'), Brit. Shells, pi. lxvi. fig. 527, 1800. 

 Voluta pallida Montagu, Brit. Test., p. 232, 1803.

Habitat. West Indies ; one dead specimen dredged at Station 247, off 

 Grenada, in 170 fms., soft gray ooze, bottom temperature 53°.5 F. 

 This species probably lives in shallower water. 



Section'? VOLUTELLA Swainson. 



Volutella lacrimula Gould.

Habitat. Off the coast of Georgia, in 400 fms., Gould. Off the coast of 

 North Carolina in 17 to 124 fms., sand, U. S. Fish Commission. Lon. of 

 shell, 2.8 ; lat. 2.0 mm. 



Volutella (lacrimula var.?) hadria Dall. 

 Volutella lacrimula Dail, Proc. U. S. Nat. Mus., VI. p. 324, 1883. 



Habitat. Mud fiats at Cedar Keys, Florida, Hemphill. 



Shorter, wider, and with the lip less prominent on top of the spire, than 

 in the typical lacrimula Gould. The two anterior plaits are subequal and 

 much larger, and extended outside the aperture beyond the two subequal small 

 posterior plaits in V. hadria, while in V. lacrimula they diminish evenly
