658 MR. E. J. MIERS ON A COLLECTION OF [Juiie 19, 



This species, of which unfortunately but a single specimen exists, 

 in bad condition, is distinguished by the unequal-sized hands and 

 the coloration (there being no trace whatever of banded markings on 

 the legs) from the other American species of the genus. The 

 abdomen is imperfect. In the form of the hands it most nearly 

 resembles C. vittatus, Bosc, of wbicli specimens from Charleston 

 Bay, Carolina, are in the national collection, presented by the 

 Smithsonian Institution. 



The following American species of this genus in the collection of 

 the British Museum are apparently undescribed. 



Clibanarius CARNESCENS, sp. n. (Plate LXVI. fig. 2.) 



Carapace with the frontal median tooth very small, acute. Eye- 

 peduncles slender, and a little shorter than the anterior margin of 

 the carapace, their basal scales small, and denticulated on tlieir 

 external margins. External antennae with their basal scales denticu- 

 lated on their inner margins, and ciliated towards their apex, reach- 

 ing very little beyond the extremity of the penultimate joint. An- 

 terior legs with the hands very small, oblong-oval, and not broader 

 tliau the wrists, with strong scattered granules, and tufts of short 

 hairs. Ambulatory legs with the tarsi very long, curved, not com- 

 pressed, much longer than the penultimate joints, with tufts of short 

 hairs. Colour orange-pink, with 4 broad alternating vittse of darker 

 colour on the legs. Length to base of abdomeu 9 lines. 



Kab. Cayenne. (Coll. Brit. Mas.) 



Clibanarius speciosus, sp. n. (Plate LXVI. fig. 3.) 



Carapace with a very small acute median frontal tooth, and with 

 the anterior margin but slightly oblique at the bases of the external 

 antennae, postfrontal suture nearly obsolete. Eye-peduncles slender, 

 and about as long as the frontal margin of the carapace, with their 

 basal scales small, narrow, and denticulated on their inner margins 

 toward the apex. External antennae with tlie last joint of the pe- 

 duncle more than twice as long as the penultimate, and with the basal 

 scale slender, reaching a little beyond the extremity of the penulti- 

 mate joint. Anterior legs with the hands oblong-oval, equal, rather 

 closely and finely granulated, and clothed with short hairs. Tarsi 

 of the second and third pairs of legs longer than the penultimate 

 joint, with longitudinally-seriate close-set tufts of rather long hairs. 

 Colour grey, or chocolate-brown (in dried specimens) ; ambulatory 

 legs with eight longitudinal whitish narrow vittae. Length of cara- 

 pace 1 inch. 



Bab. Brazil. (Coll. Brit. Mus.) 



It differs from C. brasiliensis, Dana, U.S. Expl. Exp. Crust, 

 p. 467, pi. xxix. fig. 7, in the much longer tarsi. 



Clibanarius lordi, sp. n. (Plate LXVI. fig. 4.) 



Resembles the preceding species in coloration &c. The ophthalmic 

 scales, however, are very small, ovate-acute, and entire ; the basal 

 scales of the external antennae very short, not reaching to the ex-
