were taken at depths of less than no feet. The stalked, flared-goblet- 

 shaped Echinoclathria beringensis (Hentschel) was common at Eluit- 

 kak Pass, as was also Halichondria lamhei Br^nsted. Specimens of 

 the former species from Eluitkak Pass were larger (up to 9 inches 

 across) than from any other station, although this species occurred 

 in practically every haul from depths greater than no feet, up to 

 741 feet. Since there is a strong current at Eluitkak Pass and the 

 water is often very muddy and sometimes somewhat diluted, the 

 ability of this sponge to thrive is remarkable. Often quantities of mud 

 could be squeezed from a specimen. It is muddy white or grayish in 

 color and has a disagreeable odor. A copepod, probably of a new 

 species, is often found in large numbers on the inner face of the 

 "goblet." 



From a depth of 522 feet a portion of a Polymastia andrica de Lau- 

 benfels was dredged. This sponge, which was in the form of a small- 

 bore cylinder, was a beautiful rose red in color. 



From a depth of 741 feet two specimens of a new sponge, Craniella 

 craniana de Laubenfels, were dredged, and a third at 438 feet. The 

 first two specimens were from a worm-tube and mud bottom, the 

 other from a stony bottom. All were greenish gray in life. The largest 

 specimen was approximately 2 inches in diameter and 4 inches high. 

 The long spicules of this sponge are massed in cone-shaped projec- 

 tions arranged in a manner that caused the stafif to refer to the ani- 

 mal as the "pineapple sponge." At least two species of somewhat 

 amorphous sponges, identified as Myxilla incrustans (Johnston) 

 Lundbeck and Topsentia disparilis (Lambe) Burton, were often found 

 completely surrounding a group of barnacles {Balanus rostratus 

 apertus Pilsbry) except for the apertures of the barnacles. 



The color of sponges does not last many months in preservative. 

 Some of the yellow sponges at Point Barrow even faded in the labora- 

 tory before they were placed in preservative. One unusually bright 

 one faded to a pale yellow while preparations were being made to 

 photograph it. Other sponges that were referred to as a "dirty yel- 

 low" faded to a dirty white before they could be preserved. 



The collection of sponges was turned over to Dr. M. W. de Lauben- 

 fels who identified (de Laubenfels, 1953) and described 10 species, 

 3 of which were new and included i new genus. Unfortunately, not 

 all the material was identified. 



Phylum COELENTERATA 



At least in number of individuals, if not in number of species, the 

 coelenterates at Point Barrow are extremely abundant. Six or seven
