ON CRUSTACEA BROUGHT BY DR WILLEY FROM THE SOUTH SEAS. 655 



The colour is brightly and on the whole symmetrically marbled with brown and 

 yellowish tints. The head is rather dark, with a transverse pale line in two portions 

 near the front and pale markings at the back. The legs are longitudinally striped 

 above with brown. Length, 11 mm., breadth, a little over 5 mm. 



Habitat. Lifu, Loyalty Islands. 



This interesting species is named in compliment to M. Aflrien Dollfus.

Although this species belongs to the countries surrounding the Mediterranean, 

 I feel obliged to assign to it specimens from the South Pacific, which are indeed 

 smaller in size and different in colour, but otherwise show no appreciable differences 

 that I can detect. 



The body is very convex. The prosepistome is convex, scarcely passing beyond 

 the front. The eyes are small, with about 12 ocelli. The second antennae have the 

 earlier joints proportioned as in C. dollfusi, but the last joint of the peduncle and 

 the flagellum rather longer than in that species, the first joint of the flagellum half 

 as long as the second. The first segment of the peraeon has the lateral margins 

 sulcate and cleft at the distal end ; the duplicature is strongly expi-essed in the 

 second segment. The broad short telson has the wide basal part slightly longer than 

 the distal, of which the apical margin is very feebly convex. The uropods have a 

 broad apical margin closely fitting between that of the caudal and fifth segments ; 

 the inner rami not reaching the apex of the telson, the outer minute, only visible 

 above in a lateral pocket of the peduncle. 



Colour mottled with dark brown and yellow, sometimes the brown prevailing, 

 diversified with pale spots. 



Length of largest specimen rolled up, 8 nmi., unrolled it might be about 13 mm. 



Habitat. Isle of Pines, South of New Caledonia. 



Dollfus in 1892 describes 'a variety ex colore' from the Mount of Olives and 

 other Syrian localities as Armadillo officinalis, var. Syriaca. 



CUBARIS LUNDl, n. sp. 



Plate LXX c. 



Body very convex, squamose ; each segment of the peraeon having on either side 

 of the back a little pit with a small elevation in the middle of it. 



Both front and hind margins of the head concave in the centre. The pros- 

 epistome follows the frontal curve, from which it is separated by a narrow groove. 



The eyes are not very prominent, composed of numerous (ab<iut 27) small ocelli.
