Species of the Genus Paratymolus, Miers. 303 



Denison, in Queensland, two species which are referable to 

 this remarkable genus ; and one of these I have since. observed 

 in Port Jackson. One of them is a very near ally of the 

 Japanese species described by Mr. Miers ; the other is rather 

 widely separated from it, but shows sufficient agreement in 

 essential characters to justify its inclusion in the same genus. 



Paratymolus bituberculatus, sp. nov. 

 (PI. XVI. figs. 1, 2.) 



Carapace and limbs covered with a close pubescence. Ros- 

 tral spines short, blunt ; a short spine or tooth above the eye, 

 and two others on the lateral border behind it, the hinder- 

 most the largest and placed at the angle of junction of the 

 antero-lateral and postero-lateral borders ; a small conical 

 tooth situated about the middle of the postero-lateral border ; 

 gastric region with two prominent conical tubercles. Arm 

 with four small teeth on its posterior border ; wrist armed 

 with a long slender spine; hand subtriangular, the upper 

 border produced into a prominent tooth above the insertion of 

 the dactylos, outer surface ornamented with two fasciculi of 

 short stiff setee. Ambulatory legs slender, terminal joint 

 longer than the penultimate. Length of carapace 2 lines, 

 breadth 2 lines. 



Hab. Gloucester Passage, Port Denison, about 5 fathoms. 



Paratymolus latipes, sp. nov. 

 (PL XVI. figs. 3-5.) 



Carapace and limbs closely pubescent. Rostrum of two 

 broadish lobes, each armed externally with a short acute spine 

 directed forwards and slightly inwards ; antero-lateral border 

 with four acute spines, the first (the shortest) placed in front 

 of the eye, the second behind it, and the third (the longest) 

 about halfway between the second and the fourth, which 

 occupies the lateral angle ; dorsal surface smooth. Anterior 

 limbs stout ; arm provided with a few small slender spines on 

 its internal and inferior borders; wrist armed at its internal 

 and distal angle with a short stout spine ; hand compressed, 

 its outer surface ornamented with numerous granulations and 

 a few minute spinules, upper border with a row of minute 

 spinules, inner surface smooth. Ambulatory limbs laterally 

 compressed, last joint longer than the penultimate. Length 

 and breadth of carapace 4 lines. 



Hab. Port Denison, Queensland ; Port Jackson. 



The Port-Jackson specimen has the carapace rather more 

 convex than that from Port Denison, and the first pair of limbs
