42 Illustrations in British Zoology. 



first pair of hands small ; the second much larger, oval, "ser- 

 rated on the inner margin, with a toothlike process above, 

 and armed with a curved sharp claw. The joints of the wrist 

 are short ; the brachial one lengthened. The vesicular or 

 branchial processes are in pairs, oval, and compressed ; they 

 appear to consist of a bladder filled with an opaque matter, 

 and are connected with an anterior vesicle, situated just at their 

 base. The three hinder joints of the body are each furnished 

 w 7 ith a pair of slender monodactyle legs, the last articulation of 

 which is slightly curved, and, besides its tooth at the upper side, 

 is minutely serrated and grooved on the inner edge for the 

 reception of the claw. A straight intestine runs down the cen- 

 tre : but I could not observe any trace of a circulating system. 



I do not know to whom the discovery of the animal just 

 described is due ; it is probably to Montagu : but I claim the 

 subject of the second figure (b) as my own. I have already 

 given a description of it in the third volume of the Zoological 

 Journal, p. 489., where it is named 



8. Ny'mphum cocci / neum; 



and I shall not be the first to change the designation, although 

 some parts are wanting that are generally deemed essential to 

 the species of that genus. The description is as follows : — 

 Body and legs slender, of nearly equal thickness, of a uniform 

 fine transparent red colour, with the joints and tarsi yellow- 

 ish. Rostrum yellowish : mandibles like the body. When 

 magnified, a central vessel, distinguished by its deeper tint, 

 is seen running uninterruptedly through the body and legs ; 

 and the latter are somewhat clothed with very soft white 

 delicate hairs. Rostrum cylindrical, subclavate, not jointed, 

 divided beneath by a longitudinal line, terminal. Mandibles 

 two, originating from the first segment of the body, Particu- 

 late ; basal joint long, second short and ovate, armed with two 

 small equal claws. Body four-jointed ; tubercule oculiferous ; 

 eyes two ? Legs eight, three times the length of the body, 

 equal. Coxae four, articulate ; the two basal joints short 

 and equal, the two following a little longer. Thighs as 

 long as the coxae, very slightly dilated. Tibiae of two equal 

 joints, each nearly as long as the thigh. Tarsi tri-articu- 

 late, first minute, second rather long, falciform, with a few 

 teeth on their internal edge, and terminated by a single rather 

 long claw. Tail without any appendage. 



I have seen five or six specimens of this singular creature, 

 and they were all alike in size, shape, and colour ; so that there 

 can be no doubt of its being perfect in all its parts. It lives 

 among sea- weeds in Berwick Bay; and when at rest, with 

 the legs drawn up, it so closely resembles some of the fine
