Hab. Japonian. 



Coi'i/stes (Trickocera) gibhomla, De Haan, Faun. Japon. t. %. I. 4; 1. 13. f. 3. 



Small, hairy, the carapace dilated, short, setose, tuberculated, the five middle plane 

 tubercles disposed transversely ; sides ten-toothed ; front five-toothed. 

 Hab. China Sea. Japan. 



2. TRICHOCERA PORCELLANA, Adams Sr White. 



TJiorace depresso lsevi, lineis multis dentieulatis transversis obsito ; lateribus spinis quinque robustis 

 a cutis curvatis. 



Fronte valde supra sulcata, lobis duobus obtusis dente magno externe. 



Chelis lgevibus, lineis transversis dentieulatis obsitis ; digito superiore supra dentate- ; digito inferiore 

 tuberculis quatuor supra, lineis duabus longitudinalibus infra. 



Pedibus posterioribus lsevibus, pilis longis tinibriatis. 



Hab. Insulas Philippinas. 



Carapace depressed, polished, covered with numerous transverse finely-denticulated 

 lines, some interrupted and some continued into the lateral spines ; sides with five sharp 

 strong curved spines, the first and last simple, the others with small spines at their bases. 



Front deeply grooved above, with two obtuse denticulated lobes, each with a large 

 tooth externally. 



Fore-legs polished, covered with short finely-denticulated transverse lines ; claws long, 

 with the spatulate extremities abruptly curved, upper claw dentated above, with small 

 tubercles below, lower claw with four tubercles above, and two longitudinal denticulated lines 

 externally. 



Hind-legs dilated, smooth, fringed with long hairs. 



Hab. Philippine Islands. 



By Professor De Haan, the most able of modern Crustaceologists, this species would be 

 referred to the division which contains Xanlho, and we must confess that in its general 

 appearance it has some resemblance to the Chilian genus Faraxantlms of Lucas, of which 

 there are specimens in the British Museum ; with the genus Thia of the family Corystidee 

 it has some considerable analogy, and may be said, in the group Xantko, to represent that 

 family. Like the Cancer (Xantko) integer of M. De Haan, this species is of a bright yellow 

 brown, with golden hairs (in the dried state), and both species are found in the Philippine 

 Archipelago.

The genera which compose this small but very natural group have, so far as I have 

 observed, very nearly the same habits. They swim by sudden rapid jerks, like the Galathea, 

 and appear to prefer the deep pools of the coral ledges ; they are pre-eminently swimming 

 Crustaceans, progressing but badly when taken from the water. An interesting addition to
