Fig. 2. Cyrtomaia maccullochi. llathbun, right cheliped of male ( K (>2<i3), 

 natural size. 



The chelipeds, besides rows of spines customary in the 

 genus, are sparingly covered with granules and spinules. 

 The palm of the adult male is not only very thick but is three 

 times as wide at its distal as at its proximal end. 



A fine series of nine specimens was taken in the Great Aus- 

 tralian Bight, as follows : 



South-east of Eucla, Long. 130 50' E., 250-300 fathoms ; 

 one immature female. 



South of Eucla, Long. 129 6.5' E., 200-300 fathoms ; one 

 small male. 



South of Eucla, Long. 129 28' E., 250-450 fathoms ; three 

 males (one holotype) with Lepas attached, three ovigerons 

 females, two of which bear specimens of Le]#i*. 



South by west of Eucla, Long. 126 45.25' E., 190-320 

 fathoms ; one male, with Lepas attached. 



Relationships. This species resembles (J. .v///mm, 8 C. 

 pliilycero** and C. goodridgei 5 in lacking a supraorbital spine, 

 and in having the two movable segments of the antennal 

 peduncle cylindrical, not lamellate. It differs from the first 

 two mentioned in not having a branchial spine half way
