Type locality.— B&\gv&en Cave, NWi^SW^ sec. 12, T. 7 S., R. 13 

 W., Franklin County, Ala. 



Material exatnined. — Five males II ; 4 females. May 24, 1937, Alvin 

 R. Calm coll. (one male is the holotype, U.S.N.M. No. 80031; 1 female 

 is the allotype, U.S.N.M. No. 8'0032.) 



I take pleasure in naming the species for my friend Dr. Alvin 

 Robert Cahn, its collector. 



CAMBARUS (CAMBARUS) HAMULATUS (Cope and Packard (1881)) 



The species is well known from Nickajack Cave and Wine House 

 Cave, Marion County, Tenn. An additional record, a female taken 

 with 0. pellucidus aust7'alis from Shelta Cavern, Huntsville, Madi- 

 son County, Ala., March 1, 1938, by Alvin R. Cahn, is here con- 

 tributed. The sides of the rostrum of this specimen are more 

 convergent than typical and the lateral spines are very short. The 

 annulus ventralis is identical with the annuli of the Nickajack 

 female.
