GRAPSOIDEA. 371 



four and a half lines, and its length, two and one-fourth lines J border 

 at middle spinulous, the spinules passing into granules either side. 

 Hands very strongly costate, the costse in all nine in number and 

 neatly crenulate. Length of the hands in a male, fourteen lines, and 

 height, five and a half lines ; length in a female, ten lines, and height, 

 four lines ; giving very nearly the same ratio : length of upper margin 

 to finger in male, five and a half lines, or more than a third greater 

 than the height. Behind the process of the front that forms the 

 inside of the orbit, on the back of the carapax, there is a small naked 

 obtuse prominence. The specimens here measured and described 

 were from New Zealand. Krauss's figure of a South African speci- 

 men (Siidaf. Crust., pi. 2, f. 6) does not represent these naked points 

 just alluded to, and the front has throughout a granulous margin, as 

 described by Edwards, and not spinules at middle. De Haan's PL 

 dentipes (Faun. Japon., 58, pi. 8, f. 1) differs widely in having the 

 upper margin of the hand to the fingers, much longer than the fingers, 

 and many scattered granules on the hand, while they are all in 

 lines forming costse in the tomentosa; the teeth too of the third 

 joint of the eight posterior legs are coarser and fewer in the dentipes.

Carapax Icevis, glaber, margine antero-laterali 4:-dentato, fronte supernh 

 obliquh subcristato, non spinigero. Pedes maris antwi perbreves, parte 

 manus basali breviore quam alto, supra granulatd, extus lawi et non 

 costatd, carpo fere Icevi. Articulus pedum 8 posticorum Stius Icevis, 

 Articidus niaxillipedis externi Stius quadratus, parce oblongus. 



Carapax smooth and glabrous, antero-lateral margin four-dentate, 

 front above obliquely subcristate, not spinigerous. Anterior feet of 

 nude very short, part of hand preceding fingers shorter than its 

 height, granulate above, smooth externally and not costate, carpus 

 nearly smooth. Third joint of eight posterior feet smooth. Third 

 joint of outer maxillipeds quadrate, slightly oblong.
