290 MR. BELL, HOR^E CARCINOLOGIC^ ; 



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

 distinct round tuhercles, which are largest near the hase, which part is slightly hairy 

 between the tubercles ; wi'ist granulated ; hand tumid, scarcely longer than broad, with a 

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

 the outer side, without perceiitible tubercle's or teeth, and meeting only at the points. 



Length of the carapace 0*6 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. MacgiUivray 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 hau'iness or clothing of any kind. 



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

 thoracico incisui'a inter regiones hepaticam et branchialem antice terminate ; regio- 

 rdbus 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 margia 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 browTi fascia ; the hand with a small brown spot near the articulation 

 of the moveable finger; and the abdomen with orange-colom'ed 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. 



Leucosia pulchella, milii (Tab. XXXI. fig. 4). Testa seque longa ac lata, margine late- 

 raH Isevi, tenui, subreflexo ; brachiis supra et infra onmino tuberculatis ; pedipalpis 

 externis antice paulo angustatis. 



Hab. in mari Sinensi. Mus. Brit. 



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

 thin, expanded and slightly reflexed ; thoracic sinus narrow, without granulations ; front 

 obtuse, either slightly emarginate or rounded. External foot-jaws nearly as broad at the 

 apex as at ,the base. Anterior legs rather short ; the arm entirely covered with tubercles 

 above and underneath ; wrist subglobose, with a few granulations at the inner side ; hand
