226 BULLETIN OF THE 



Colubraria Swiftii Tkton. 

 Triton (Epidromus) Swiftii Tryon, Man., IIL p. 31, pi. xvi. fig. 168, 1881. 



Habitat, Station 272, in 76 fms., Barbados; also in 100 fnis., off Barbados 

 (fragment). Antigua, Swift; Samana Bay, Santo Domingo, Couthouy; Ba- 

 hamas, Rawson; Bermuda, Goode, 



There are also known from this region Colubraria testacea Mdrch (ohscurus 

 Tryon pars) ; and C. reticulatus Blainville. Specimens of C. eximius Reeve, 

 a Pacific species, have been distributed under the name of Triton parvus 0. B. 

 Adams, which is a Phos, so that Tryon has been led into the error of regarding 

 Adams's species as a synonym of Reeve's, and assigning the latter to the West 

 Indies, a habitat as yet not confirmed. It is not unlikely that Triton lineolatus 

 Conrad (Phila. Proc, 1846, p. 26, pi. i. fig. 18) may have been a 3"oung speci- 

 men of T. parvus, but Conrad's figure and description are alike totally in- 

 sufficient and unrecognizable, the type being lost, and the species should be 

 dropped from the lists. 



Subgenus RANULARIA Schumacher. 



Of this group T. cynocephalus Lamarck and T. olearium L., the latter reach- 

 ing nearly to Hatteras, are known from the region, together with the following 

 species. 



Ranularia tuberosa Lamarck. 



Triton tuberosum Lam., An. s. Vert., VII. p. 185, 1822. 

 Triton antillarum Orbigny, Moll. Cuba, II. p. 161, pi. xxiii. fig. 20, 1847. 

 1 Triton pyriformis Conrad, Journ. Acad. Nat. Sci. Phila., 2d ser., 1849. 

 Triton nodulus Morch, Cat. Yoldi, p. 109, 1854. 



Habitat. Florida, at Key West and Tortugas, Hemphill. Bermuda, Goode. 

 Antilles, Orbigny. Vera Cruz, Strebel. 



This, like several others, is found in the East Indies, and in spite of the efforts 

 of various naturalists to separate it, I am quite in harmony with Mr. Tryon in 

 his consolidation of the various synonyms. The several varieties are not geo- 

 graphically limited, and therefore cannot be regarded as anything more than 

 varieties. 



Subgenus LAMPUSIA Schumacher. 



Lampusia chlorostoma Lamarck. 



Triton chlorostomum Lam., An. s. Vert., VII. p. 185, 1822. 



Triton pulchellus C. B. Adams, Centr. Conch., p. 60, 1850 (testa jun.). 



Habitat. Off Sombrero, in 54 fms.; Station 142, Flannegan Passage, in 27 

 fms.; Stations 272 and 287, in 50-76 fms., Barbados. (Mostly young speci- 

 mens.) Bermuda, Goode. Antilles and Mexican coast generally, Morch.
