REPORT ON THE ANOMURA. 97 



Paguro<h'!^ limatulus, n. sp. (PI. X. fig. 6). 



Characters. — The anterior portion of the carapace is smooth and convex, as are also 

 the Literal borders, the median frontal projection is prominent and obtusely rounded, the 

 lateral projections are less strongly marked, with their apices obtuse ; the posterior portion 

 of the carapace is entirely membranous. 



The ocular peduncles are remarkably short, with the cornese not sensibly dilated, 

 and a few hairs are seen on their upper surface ; the apices of the ophthalmic scales are 

 rounded and entire. The antennal peduncle is two and a half times the length of the 

 eye-stalk, the acicle is long, slender, and curved ; the external prolongation of the 

 second joint terminates opposite the end of the eye-stalk, and a slight prolongation 

 is present on the inner margin of the same joint. The antennular peduncle exceeds 

 the eye-stalk by the whole length of the last joint and a portion of the penultimate 

 joint. 



The chelipedes are long and remarkably slender, with the length subequal, though 

 the right is considerably stouter. The right chelipede has the merus with its upper 

 surface crossed by transverse piHferons lines, the lower surface is slightly tuberculate, 

 and three spinules are present on the lower and outer border at its distal end ; the carpus 

 is about two-thirds the total length of the pi'opodus, with its upper surface pubescent 

 and slightly granular, while the inner border is spinulous, especially towards its distal 

 end; the upper surface of the propodus is smooth and polished, convex from side to side, 

 and with traces of granulation towards the inner margin ; the fingers arc smooth, and less 

 than half the length of the propodus, while they are provided with a few short hairs. 

 The left chelipede is unusually slender, with the lower surface of the merus tuberculate 

 and slightly pubescent ; the carpus nearly equals the propodus, its upper surface bears two 

 indistinct rows of spinules separated by a considerable interval, and a rounded swelling 

 is present on the inner and distal surface ; the upper surface of the propodus has an 

 obscurely marked central ridge, the fingers are longer than those of the right chelipede 

 and perfectly smooth above. The ambulatory limbs slightly exceed the chelipedes in 

 length ; the anterior surface of the meral, carpal, and propodal joints bears a few indis- 

 tinct pubescent ridges, the daetyli are one and a half times the length of the j)ropodi, 

 slender, and but slightly curved, their lower borders are armed with delicate corneous 

 spines, and each terminates in a yellow horny claw. 



The penultimate abdominal segment is crossed by a moderately deep transverse 

 groove ; the ultimate segment is four-lobed, with the two terminal lobes of small 

 size. 



Length of body 15 mm., of right chelipede 20 mm., of left chelipede 19 mm., of third 

 left leg 23 mm., of ocular peduncle 2 mm.
