 fathoms. 



Locality. — Station I., Tunghi Bay. 



Previously recorded from— Philippines ; Admiralty Is. ; Macclesfield Bank. 



Stellaster incei, Gray. 



This species is represented by a single specimen, in which £=285 and 

 ?■= 10. The nature of the bottom on which a certain species exists is always 

 interesting, inasmuch as it has often a distinct bearing on the individual 

 specimens ; but S. incei does not seem to be associated with any particular 

 kind of bottom. At Mergui we found it occurring on — (1) mud and stones; 

 (2) sand and mud ; (3) coral and sand ; and (4) sand and shell. 



Its bathymetrical distribution is, however, restricted. The following 

 records are noteworthy : — East Africa, 3 to 15 fathoms; Torres Strait, 6 to 8 

 fathoms; Arafura Sea, 28 fathoms; Philippines, 18 fathoms; Port Molle, 

 5 to 11 fathoms; Port Denison, 6 fathoms; Ceylon, up to 40 fathoms. 



Locality. — Station VI., Kero-Nyuni Bay. 



Previously recorded from — Korea ; Singapore ; North-West Australia; Port 

 Curtis and Albany Island ; and Mergui Archipelago (in addition to the above). 



Anthenea sp.? 



There occur in the collection seven small specimens which we have 

 referred to the genus Anthenea. They are all immature, and as we were 

 unable to identify them with any known species, we have refrained from 

 establishing a new species to include them. The following notes, however, 

 may be of interest : —

There are nine marginal plates, excluding the unpaired terminal one ; 

 these are rectangular in shape and bear no pedicellariae. 



The supero-marginal plates are tuberculated ; all, except those in the arcs, 

 bear two tubercles, while three or four are not infrequent ; the tubercles are 

 arranged transversely. The infero-marginal plates bear spines only towards 

 the extremities of the arms ; three spines sometimes occur, either clustered 

 or disposed longitudinally, never transversely.
