43. Paratelphusa (Globitelphusa) gubernatoris, Alcock. (Fig. 32.) 



Carapace flat, square, its length nearly seven -eighths its breadth, its deptli 

 less than half its length, its surface smooth to the naked eye, but under a lens 

 pitted, and finely rugulose laterally. 



Regions of carapace not defined ; a fine crescent defining the mesogastric 

 ai-ea posteriorly is all that exists of the cervical groove ; a longish shallow 

 groove separates the extremely faint epigastric crests. 



Front in the adult about two-fifths the greatest breadth of the carapace, 

 square, very strongly deflexed, its edge nearly straight, with pronounced orbital 

 angles. Outer orbital angle not prominent, the upper and lower borders of the 

 orbits meeting flush at that point. 



Antero-lateral borders of carapace short, and nearly straight from the orbit 

 backwards, the lateral epibranchial denticle being marked by a little nick. 



Epigastric crests just distinguishable ; post-orbital crests only just dis- 

 tinguishable at their outer ends near the lateral epibranchial denticle. 



Abdomen of adult male a broad-based triangle in outline, the three 

 terminal segments being much contracted ; in the 6th segment the distal 

 breadth slightly exceeds the proximal breadth and equals the length ; the 

 7th segment has a broadly-rounded apex and its length equals its proximal 

 breadth. 



The mandibular palp is of the already described Paratelphusa type, the 1st 

 and 2nd segments being indistinguishably fused and the terminal segment being- 

 bifurcate from the base. 



In the external maxillipeds the exopodite is longer than the ischium and is 

 usually non-flagellate, though a minute papillar vestige of a flagellum is 

 occasionally present ; the ventral surface of the ischium is not longitudinally 

 grooved ; the merus is much broader than long and its greatest length is at the 

 outer border. 



The antenuular fossae are of normal width and are widely open to the 

 orbits as usual, the opening being loosely filled by the antennal peduncle as 

 usual. (These points are mentioned in order that the species may not be 

 confused with another superficially similar species from exactly the same 

 locality). . The basal (true 2nd) antennal joint is of fair size, but the succeeding 

 joints are extremely small, and the flagellum is minute. 



Chelipeds unequal in adults of both sexes, most so in the adult male ; to 

 the naked eye they appear smooth ; the inner angle of the carpus is merely 

 pronounced, not spiniform ; in the smaller cheliped the fingers are about as 

 long as the palm and are fairly straight ; in the larger cheliped the palm is 

 nearly as high as long, the fingers are about as long as the jmlm, one tooth in 

 the fixed finger is conspicuously enlarged, and in the male there is a wide gap
