than those of transversa , and the median frontal furrow 

 is more distinct. 



Telphusa angustifrons A. M. E., inhabiting Cape York 

 together with Telphusa transversa , is also closely allied. 

 In Telphusa angustifrons , indeed , there is also no hiatus 

 or emargination between the lower margin of the orbits 

 and their external angle, and the impressed line on the 

 ischium-joint of the outer foot-jaws is situated as close to 

 the internal margin of the joint as in Geotelphusa picta , 

 but Telphusa angustifrons may , at first sight , be recognized 

 by its less enlarged ceph alothorax. The measu- 

 rements of a type-specimen of Telphusa angustifrons in the 

 Paris Museum are the following: 9

I refer to this species two young specimens ((ƒ, 9) col- 

 lected on the Fidji Islands and purchased from the Museum 

 Godeffroy. 



One of these specimens I sent to Dr. Hilgendorf, who 

 kindly informed me that it agrees quite well with the 

 type-specimen of Telph. transversa, but that the chelipedes 



1) If these two species are really identical, the name given by von Martens 

 should have the priority. For, though Milne Edwards' paper was presented to 

 the »Société entomologique de France" in June 1868 , the name crassa appears 

 no sooner than in the Zoological Record for 1869, whereas Telphusa transversa 

 is already recorded in that for 1868, and von Martens himself was at that 

 time the recorder.
