156 "ENDEAVOUR" SCIENTIFIC RESULTS. 



"The orbits are large. There is a large tooth in the 

 middle of the upper orbital border, which is joined by a 

 very slight curve to the large obtuse tooth at the inner 

 supraorbital angle; these two together form a considerable 

 projection over the orbit. The suborbital border is denti- 

 form, and is easily seen in a dorsal view, it being situated 

 outside the large projection of the upper border. The outer 

 angle seems to form a continuous line, but if the tomentum 

 be scraped away it shows that the borders are separated 

 by a groove. The antero-lateral borders are cut into four 

 teeth, the first being the smallest and on a much lower plane 

 than the other three, it being on a slightly lower level than 

 the outer orbital angle. The second and third are large, 

 the distance between them being distinctly less than that 

 between the first and second or third and fourth. The 

 latter is small, and is situated behind the cervical groove. 

 There is a small tubercle, which may either be acute or 

 very flat, on the ridge behind the cervical groove, and 

 almost at the base of the fourth tooth. Postero-lateral 

 borders are slightly convergent and are convex. 



"There is a small acute tubercle on the subhepatic region 

 situated midway between the first tooth of the antero-lateral 

 border and the endostome, and another smaller one at the 

 base of the suborbital lobe. 



"The crest of the merus of the cheliped bears a few 

 small granules under the tomentum. The carpus is nodular, 

 and at the inner angle there is a sharp tubercle covered 

 by a tuft of long silky hairs. The tomentum on the outer 

 surface of the hand forms longitudinal ridges. Both the 

 inner and outer surfaces of the movable and immovable 

 fingers are strongly grooved, and along these grooves the 

 tomentum grows. The inner surface of the hand and 

 fingers, and the lower edge of the merus, bear the long 

 silky hairs already mentioned. There is a space between 

 the fingers at their base. In some specimens they meet 

 only at the tips, while in others they meet the last half 

 of their length. There are seven or eight teeth along their 

 outer borders, which interlock perfectly when the fingers 

 are closed. 



' ' The first and second ambulatory legs bear strong spinu- 

 lar nodules on their carpi and propodi. Both the third 

 and fourth pairs are flattened, and have no nodules ; the 

 fourth pair being dorsally situated." 



The sternal sulci of the female end far apart in a line 

 between the coxae of the first and second ambulatory legs.
