from one of the anchor teeth near the apex of the head and another 

 smaller protuberance near the end of a certain spine. 



Specimen C is beautifully preserved, and its sponge body is nearly 

 straight, phalluslike, and quite similar to the outer configuration of 

 various specimens obtained from the southern part of Japan (espe- 

 cially to the specimen photographed on Plate 6, figure 1, of Ijima's 

 Contribution I). 



Parietal ledges are present but not so prominently developed. 

 They run irregularly in places, and may approach 1 mm in height. 

 Their free edge is fairly even, frequently being either blunt or sharp. 

 The numbers of beams are as follows : Circular, 39 ; longitudinal at 

 upper end, 31; longitudinal at middle, 28; longitudinal at lower 

 end, 23. 



Spimdation. — The oxea of the oscular margin are prominent, being 

 usually slightly curved compass-needlelike spicules with two very 

 weak oppositely placed tubercles at their center and sharply pointed 

 at both ends. They occur in tufts or projecting singly from the der- 

 mal surface of the oscular margin and with the inner one-third to 

 one-fourth of their length embedded in the oscular margin. They 

 measure about 715/x to 780^ long and 8/t thick at their center. 



The oxyhexaster is represented in greater numbers, as compared 

 with the other specimens. It is especially abundant in the paren- 

 chyme, differing from the specimens from Station 4878, which have 

 fewer oxyhexasters among the parencyhmalia than in the subder- 

 malia and subgastralia. The same abnormality of the basalia occur- 

 ring in the specimen from Station 4878 is also found in this specimen.

Two large specimens of C. m. rugosa were trawled up from a 

 depth of 103 fathoms off Kagoshima Gulf (Station 4936). Both 

 are badly macerated. One, a large fragment, is probably all the 

 body proper of a large sponge, and the other is a nearly complete 

 colony with a distinct large stalk, which during preservation was 

 broken from the body. The stalk expands somewhat abruptly
