700 " THETIS " SCIENTIFIC RESULTS. 



in 5-7 fathoms ; Torres Strait, littoral, and in 10 fathoms ; Cape 

 York; Port Molle, in 12 fathoms; Port Denison ; channel 

 between Albany and Somerset Islajids, in 8-12 fathoms; off 

 Bool)y Island (10° 36' S. lat., 14° 55' E. long.), in 6 fathoms. 



Range. — Honf( Kong, Singapore, and the Philippine Islands 

 southward to Northern Australia, on the north-east coast 

 extending south to Port Curtis. 



Femarks. — It is very curious that this species does not occur 

 in the broad armed and generally robust phase except along the 

 Australian coast; specimens from Singapore and Hong Kong 

 always, so far as known, have narrow slender arms, which are 

 well rounded dorsally. On the other hand, the robust phase of 

 C. pecthiata is common throughout its range. It is not uncommon 

 to find specimens of C. fectinata with three or four robust arms, 

 the remainder being slender, and much longer, but I never saw 

 this variation in C. Solaris. 



Lamarck's original material consisted of six fine specimens. 



The fine specimen taken by the "Alert" at Port Molle has no 

 cirri ; the centrodorsal is reduced to a pentagonal plate which is 

 not quite sunk to the level of the dorsal surface of the radials.
