63. Telphttsa Callianiea, n. sp. (PI. VI. figs. 1-3.) 



(Compared with tlie type specimen of TelpTiusa grapsoides, 

 White, and with the type specimens of T. Jiydrodromus, Herbst, 

 T. Jagori, T. Mart., and T. subquadrata, Grerst., which are pre- 

 served respectively in the British Museum and in the Museum at 

 Berlin.) 



Fifteen specimens (eight S, seven $ ) of this pretty little 

 Telplmsa are in the Collection ; thirteen of which were collected 

 in the mangrove-swamps of Kisseraing Island, the two others in 

 Sullivan Island. 



This new species is closely allied to the previous species, 

 and, I presume, also to T. angustifrons, A. M.-Edw., a species 

 inhabiting Cape York. It belongs to the group in which the 

 postfrontal ridge is interrupted not only in the middle by the 

 median frontal furrow, but also on each side of the latter in the 

 middle, and again near the lateral margins ; so that the two median 

 portions are more advanced than, and wholly separated from, the 

 lateral, which do not reach the epibranchial tooth. 



The cephalothorax is rather narrow, though broader than long. 

 The proportion of the distance between the epibranchial teeth to 

 the length of the cephalothorax (the abdomen being excluded) 

 is about 16 : 14, both in the male and in the female. The 

 cephalothorax presents its maximum of breadth immediately 

 behind the epibranchial teeth ; so that the anterior half of the 

 lateral margins is slightly convex outwards and the posterior 

 faintly concave. The upper surface of the carapace is rather 

 depressed and flattened ; anteriorly it is somewhat convex, and 

 the front is almost vertically deflexed downwards. In the female 

 the upper surface is a little more convex. 



The front is of moderate breadth ; the breadth of its anterior 

 margin is in proportion to the distance of the epibranchial teeth 

 almost as 6 to 16, so that the front measures a little more 

 than a third of the distance of the epibranchial teeth. The 

 anterior margin of the front, which is nearly straight, pre- 

 sents only a very slight median sinus, and is almost at a right 

 angle with the upper margins of the orbits. In T. liydro- 

 dromus, Herbst, however (a species inhabiting the island of 

 Ceylon, and closely allied to our T. Callianird), these angles 

 are very oblique and rounded, according to Dr. Hilgendorf, 

 who kindly compared for me this species with all the Tel- 

 jpJiuscB of the Zoological Museum of Berlin. Dr. Hilgendorf
