SCYPHIDIUM NAMIYEI (Ij.) 



Plate VI., %s. 9-17. 



Vitrollnla namiyei, Ijima, '98, p. 48. 



Two complete specimens and some fragments of this species 

 were obtained by Kuma in one haul of the long-line at Outside 

 Okinose by the Iwado-line, fi'om a depth of about 4o7 m. (250 

 faths.). 



Both complete specimens (PI. VI., %. 9) present a laterally 

 compressed, irregularly shaped, moderately thick-walled, pouch- 

 like body of a moderate size. Above, there exists in both a 

 secondarily formed osculum l)esides the primary. Below, the 

 somewhat contracted base had evidently been firmly fixed to the 

 substi'atum by an irregular attachment surface or rather by a 

 number of such. 



The larger specimen (PI. VI., fig. 9a) is Qiß mm. high. A 

 cross-section of the laterally compressed body at its widest j)art would 

 present an oblong outline, Ö4 mm. long and about half as broad. 

 The wall is about 5 mm. thick in the middle of the body. The 

 upper end is occupied by a large, irregularly oval, sharp-edged 

 osculum. To one side of this and well apart from it on the 

 sagittal edge of the l)ody, there is a papilla-like bud, the rounded 

 apex of which shows a secondary osculum of 2 mm. diameter. 

 This leads into a small gastral cavity about 5 mm. deep, which 

 does not stand in open communication with the principal gastral 

 cavity. The specimen also shows on one side an oval-shaped gap 

 in the wall, leading into the main gastral cavity. 



The smaller sj)ecimen (fig. 9 b) is 5Q mm. high. It is widest 

 at the upper end, measuring 41 mm. in the longest direction
