290 MR. BELL, HOR.E CARCINOLOGIC^E ; 



interrupted in the middle. First pair of legs rather short and thick ; the arm covered with 

 distinct round tubercles, which are largest near the base, which part is slightly hairy 

 between the tubercles ; wrist granulated ; hand tumid, scarcely longer than broad, with a 

 slight granulated carina on the outer and inner margins ; fingers flattened, carinated on 

 the outer side, without perceptible tubercles or teeth, and meeting only at the points. 



Length of the carapace 06 in. 



Colour light brown; the spots on the carapace small, of an angular form, and red 

 colour ; a large red spot on the upper surface of the hand. 



A single female specimen was found by Mr. Macgillivray on the eastern coast of 

 Australia. 



This is a very remarkable species, not only from its general form and character, but 

 particularly as being almost the only one of the genus which exhibits the slightest appear- 

 ance of hairiness or clothing of any kind. 



Letjcosia Cumingii, mihi (Tab. XXXI. fig. 3). Testa suborbiculari, margine laevi; sinu 

 thoracico incisura inter regiones hepaticam et branchialem antice terminato ; regio- 

 nibus branchialibus valde tumidis. 

 Hab. ad insulas Philippinas. Mus. Brit. 



Carapace suborbicular, of equal length and breadth ; the margin rounded, not granu- 

 lated ; front obtuse, rounded ; thoracic sinus deep, terminating anteriorly in a deep notch, 

 corresponding with an incision in the margin between the hepatic and branchial regions ; 

 the latter region very tumid. Pedipalps rather broad, the outer margin slightly curved. 

 Anterior legs stout, the arm short, with tubercles at the base and sides, beneath with a 

 triangular area smooth; wrist rounded; hand nearly as broad as it is long, slightly 

 carinated at the sides ; fingers meeting only at the points, the moveable one grooved 

 longitudinally. 



Length of carapace 0*5 in. 



Colour ; the carapace pale yellowish-white, with yellow markings. The fingers marked 

 with a transverse brown fascia ; the hand with a small brown spot near the articulation 

 of the moveable finger; and the abdomen with orange-coloured spots on the anterior 

 part. 



One of the most remarkable of the genus, and distinguished at once by the deep notch 

 behind the hepatic region and the swollen form of the branchial.

Carapace rhomboidal, as broad as it is long, the lateral margin without granulations,
