RHABDOCALYPTÜS MOLLIS. 253 



Together with the above bodies or in places where one might 

 expect to find them, there not nncommonly occur roundish, oval 

 or irregularly contracted cells of pale appearance and each con- 

 taining a darkly stained nucleus (fig. 20, c). They measure 7i- 

 12/^ or more across. An enveloping membrane is distinguishable; 

 the contents are thinly granular. I take these cells for old 

 thesocytes, which have lost the fat-like products by consumption.

The specimens I have seen of this species number not less 

 than a dozen. Most of them belonged to Mr. Alan Owston. 

 That all came from the Sagami Sea there can be no doubt, but 

 only in the following three cases can the localities be more exactly 

 stated: Homba (about 572 m. depth), where Kuma obtained two 

 very small specimens together with R. capillalus ; off Odawara 

 in the Province of Sagami (about 500 m.), at which locality I 

 myself obtained a fragment attached, together with a number of 

 other animals, to the carapace of a JIacrocheirus kcempferi ; and 

 the " Albatross " Station 3697 (about 4 kilom. off the mouth of 

 Sakaw^a River in Sagami, 265-120 fms., black volcanic mud), 

 where a tubular fragment of the species was trawled up by the 

 " Albatross " (1900) together with Acanthascus cactus.
