none of them very large. In a second (female) specimen of un- 

 known locality which is in tlie collection, and appears to belong 

 to this species, the number of spines varies from three to four. 

 The terminal segment is almost orbiculate in outline.

Carapace elongate-ovate and convex above. Front 3-toothed, 

 the teeth triangular, and ending in long spines, the median tooth 

 rather less prominent than the lateral. There is a small median 

 spine immediately behind the groove defining the anterior margin 

 of the gastric region, and four spines on the antero-lateral margins, 

 of which the first is long and the last very small. The eye-pedun- 

 cles are very slender ; and their penultimate about equals the last 

 joint in length. The flagella of the antennae have a series of long 

 Jiairs. The anterior legs have the arm short, with a long spine on its 

 inferior margin ; wrist with a strong triangular tooth on the upper 

 margin at the distal extremity, behind which is a spine ; palm 

 slightly rugose externally, with two spines on its outer surface, 

 one on its inferior margin at its infero-distal angle, and two very 

 strong spines on its anterior margin and on the upper margin of 

 the mobile finger. Terminal joints of the second and third legs 

 strongly falcate, those of the second pair broader and shorter 

 than those of the third pair, those of the fourth pair but slightly 

 falcate, the fifth pair slender, small, and monodactyle. Tail- 

 segments (the last excepted) short, with horizontal ovate lateral 

 lobes; the last joint of the male is twice as broad as the foregoing 

 at base, as broad as long, with the sides converging to the distal 

 extremity. 



Hah. Chili, at Tome, in Bay of Talcahueno (Philippi) ; Bay of 

 Valparaiso (Coll. Brit. Mus.). 



The specimens described by Philippi were found by Herr Ph. 

 Germain on the sea-shore. The specimen (a male) in the British- 

 Museum collection was found by fishermen in deep water in the 

 Bay of Valparaiso, where it is stated to be of rare occurrence. The 

 length of its carapace is nearly 1 in. 2 lines.
