Hangklip N. by E., distant 12 miles. 13 fathoms. 1^,2 juv. ; 

 oft' Cape Hangklip. 2 ovigerous 9 9 . s.s. " Pieter Faure." 11/11/02, 

 26/4/00, 19/11/03, and April, 1898. (S.A.M. Nos. A2709, A3827, 

 A3885, A4076 "and A4117 respectively.) 



All the localities are situate in False Bay. The specimens from the 

 " Pieter Faure " collection were all taken out of galleries in various 

 kinds of sponges, one being also found in the central cavity of a 

 Leuconia-like sponge. 



The following specimens are kept separate for these reasons : they 

 appear to be exactly like the typical form, but differ in the shape of 

 the frontal lamina. This has the basal portion rather deeply set and 

 more or less covered by the epistome, so that it appears wider than 

 long. It thus presents a very different appearance from that of the 

 typical specimens. In these latter the vvhole of the frontal lamina can 

 be seen without depressing the epistome, and moreover it is consider- 

 ably narrower. As in the typical form a certain amount of variation 

 can be observed, so that a perfect transition from one to the other may 

 yet be found. 



Unfortunately no adult $ was found amongst these specimens, so 

 their specific identity must for the present remain doubtful. 



In the 9 the front margin of the head is not quite so prominent 

 and is less distinctly margined, and the dorsal surface shows not the 

 slightest trace of a longitudinal concavity. 



Length: Ovigerous 9 911*5 mm. ; breadth: 4' 5-5 mm. 



Colour : As noted above.

CRYPTONISCAN PARASITE. 



On one of the specimens A4084 were found 2 Cryptoniscan larvae, 

 which may be referable to the genus Clypeoniscus (see p. 431), but as. 

 no female was present their correct identification remains uncertain.
