Cristellaria aculeata Flint (not D'Orbigny), Rep. U. S. Nat. Mus., 1897 

 (1899), p. 318, pi. 66, fig. 3. 



Description. — Variety differing from the typical in the larger pro- 

 portion of the uncoiled part and especially the greater development 

 of spines on the periphery and the lack of the secondary ornamenta- 

 tion between the sutural lines, the wall there being smooth. 



Distribution. — Type-specimen (U.S.N.INL Cat. No. 18915) from 

 Albatross station D2377, in 210 fathoms (381 meters), in the north- 

 ern part of the Gulf of Mexico. At the type station this species 

 occurs abundantly, and specimens were also obtained from two other 

 stations in the northern part of the Gulf of Mexico, closely adjacent 

 to the type station. Flint's specimens referred to Oristellaria aculeata 

 are the same as this, coming from two of the stations which are re- 

 corded here.

Specimens have been recorded under this name from a few Atlantic 

 stations. Flint records and figures specimens from off the coasts 

 of Florida and South Carolina, 60-90 fathoms (110-165 meters). 

 Pearcey records it from 56 fathoms (102 meters), Burdwood Bank. 

 The other Atlantic records are those given by Heron-Allen and 

 Earland,"" who record it from off Clare Island, and^" "few, not 

 typical," west of Scotland.
