Lot Collected at— 



Number and description 



A Station 4890, 10-20 miles SW. of Goto Islands, 135 fathoms. 



B ' Station 4934, off Kagoshima Gulf, 103 fathoms 



Several fragments. 

 One, nearly complete. 



Of the scopulae the sharj^ brakelike bend of the terminal branches, 

 which characterizes the spicules of the species, does not constantly 

 occur, some scopulae being occasionally found with straight terminal 

 branches, as in P. carteri. In addition to the common discohexaster 

 like that in the typical species, another with widely divergent termi- 

 nals is occasionally found scattered in the parenchyme as well as in 

 the hypoderm. 



The greatest variations of the spicules of this sponge are to be 

 found in the free hexactins, which are abundant in the parenchyme, 

 but these variations in spiculation are correlated with the parts or 

 regions of the sponge body where they enter into the formation 

 of the dictyonal framework. 



Genus PERIPHRAGELLA Marshall, 1875 



PERIPHRAGELLA ELISAE Marshall 



Periphragella elisae Marshall, Zeit. Wiss. Zool., vol. 25, suppl., pp. 177-180, 

 pi. 12, fig. B, 1875 ; Zeit. Wiss. Zool., vol. 27, p. 123, 1876. 



A large nearly complete specimen, resembling in outer configura- 

 tion the Challenger specimen brought from Enoshima, Japan, by 

 Doderlein, was obtained from a depth of 369 fathoms in Sagami Bay, 

 near Jogashima (Station 5088). It has the form of a nearly 

 straight cup, or funnel, 137 mm in length, and rises, with a round 

 hollow stalk of 16 mm diameter, from an irregularly formed basal 

 plate 40 mm broad, and gradually expands upward toward the round 

 terminal opening, which is 40 mm in diameter. Most of the narrow 

 tubular branches, which project externally from all the surface, are 

 injured toward the ends of the tubes. 



The discohexaster in the parenchyme differs slightly from that of 

 the type specimens in having broad, long principals. From these 

 arise five or six short but strong terminals, which are half as long 

 as the principal. Distally they are weakly bent outward, becoming 

 perianthlike in shape. On the form of the discohexaster the P. elisae 

 from Japanese waters, described by Schulze in the Challenger re- 

 port, ought to be separated from the typical species, as it has long, 

 slender, widely divergent terminals, nearly twice as long as the 

 principals.
