Cristellaria cultrata (Montfort), var. decorata Cushman, Proc. U. S. Nat. Mus., 

 vol. 51, 1917, p. 656. 



Description. — Variety differing from the typical in the addition of 

 a distinct type of ornamentation, consisting of a large umbilical knob 

 above the umbilical region, and the sutures 

 with costae which are gradually larger 

 toward the periphery. 



Distribution. — Type specimen (U.S.N.M. 

 No. 9121) from Albatross station 5113 in 

 159 fathoms (290 meters), China Sea off 

 southern Luzon. It also occurred at the 

 following Albatross stations: D5121, in 108 

 fathoms (198 meters), east coast of Min- 

 doro; D5222, in 195 fathoms (356 meters), 

 between Marinduque and Luzon, bottom 

 temperatm-e 52.8° F. (11.5° C); D5260, in 

 234 fathoms (428 nxeters), off southeastern Mindoro, bottom tempera- 

 ture 51.4° F. (10.7° C); and D5590, in 310 fathoms (567 meters), 

 Sibuko Bay, Borneo.

CRISTELLARIA RENIFORMIS d'Orbigny. 



Cristellaria reniforrnis d'Orbigny, Foram. Fobs. Vienne, 1846, p. 88, pi. 3, figs. 

 39, 40.— H. B. Brady, Rep. Voy. Challenger, Zoology, vol. 9, 1884, p. 539, pi. 

 70, figs. 3a, 6.— Cushman, Bull. 71, U. S. Nat. Mus., pt. 3, 1913, p. 65, pi. 30, 

 fig. 4; pi. 33, fig. 1. 



Single specimens referable to this species were found at the follow- 

 ing Albatross stations: D5439, in 940 fathoms (1,719 meters), west 

 coast of Luzon, bottom temperature 36.7° F. (2.6° C); D5613, in 

 752 fathoms (1,375 meters). Gulf of Tomini, Celebes; and D5668 

 in 901 fathoms (1,648 meters). Macassar Strait, bottom temperatm-e 

 38.2° F. (3.4° C). 



These stations are all in comparatively deep water, with a cold 

 bottom temperature, and compare rather well in conditions with 

 most of those recorded in the ChaUenqer report for this species in 

 these two respects.
