ATTSTBALIAN MAIACOSTBACA. 159 



small teeth above. Carpus of the second and third legs with a 

 minute acute spine at the distal end of its upper border. Am- 

 bulatory legs with a few scattered fasciculi of hairs. In speci- 

 mens preserved in spirits the chelipedes (with the exception of 

 the fingers and the carpus of the ambulatory legs) are green ; 

 the fingers are colourless ; the propodos of the ambulatory legs 

 is light dull red ; the basal portion of the dactylus dark purple, 

 the distal portion light yellow with a black tip. The rest of the 

 surface is washed with light brown and olive. Length about 

 one inch. 



Claremont Islands, Queensland coast, on coral reef (W.A.H., 

 H.M.S. "Alert.") 



Genus Clibanabias, Dana. 

 Anterior feet sub-equal. Fingers moving in a horizontal 

 plane, corneous at tips, spoon-excavate. Front having a small 

 mesial tooth as a rostrum. [Z).] 



300. Olibanarius striolatus. A.M. 



Olibanarius striolatus, Dana, U.S. Explor. Exped., Crust., i., 

 p. 463. 



Anterior region of the carapace nearly quadrate. Eyes 

 slender, about as long as the anterior margin of the carapace, 

 basal scale narrow, bidentate at apex. Anterior feet sub- equal. 

 Hands short and, with the carpus, spinituberculate above and 

 pilose, the left in the male slightly the larger. Feet of second 

 and third pairs short hirsute in tufts on the upper and lower 

 sides, tarsus subterete, as long as the preceding joint, fifth joint, 

 left side, of third pair slightly convex and having a right-angled 

 edge above. [_D.] 



A specimen of a Olibanarius from Holborn Island, Port 

 Denison, Queensland, agrees tolerably well with Dana's descrip- 

 tion and figure of C. striolatus, but the spines on the hand and 

 carpus are longer, and the ophthalmic scale has not quite the 

 shape represented in the figure. 



Family OEJSTOBITIDM 



Internal antenna greatly elongated, the first joint often longer 

 than the eyes, strongly deflexed. Palp of the external maxilli- 

 pedes without a flagellum.
