-FROM THE INDO-PACIFIC AND WEST AFRICA. 301 



they are united for a fifth of their length with the outer flagella and are slightly 

 serrated. 



The external maxillipedes extend a third of their terminal joint beyond the peduncle 

 of the lower antennae. The legs of the tirst pair, which are 42 mm. long, project with 

 little more than their hands beyond the tip of the antennal scales. The slender carpus 

 is 18 mm. long, and 1"33 mm. thick at the distal end; it is almost three times as long 

 as the chela, which is 666 mm. long and the fingers of which are slightly longer than the 

 palm. Only one leg (fig. 14) of the second pair is still present ; this leg is a little longer 

 than the animal. The merus extends for about a third of its length beyond the antennal 

 scales; it is straight and thickens slightly to a little behind its distal end, its greatest 

 width being 6'5 mm. ; this joint appears consequently five times as long as thick. The 

 carpus is one-fourth longer than the preceding joint ; it is slender and thickens slightly 

 and rather regularly towards the distal end, its diameter being here about one-eighth 

 of the whole length. The carpus is, however, not quite straight, but very slightly 

 curved, so that the inner margin appears a little concave, the outer very slightly convex. 

 The jjcdm has about the same length as the merits and is as much shorter than the 

 carpus as the latter. The almost quite straight palm is cylindrical., presenting over 

 its whole length a diameter of 4 mm., so that this joint is 8 times as long as thick. The 

 fingers, which are thickly covered with a icoolhj felt, quite close together; the immobile 

 fi.nger is straight, the dactylus, however, very slightly arcuate. The immobile finger is 

 armed with a small conical tooth, about 0-75 mm. high, at one-third of its length from the 

 articulation, and between this tooth and the articulation seven or eight smaller teeth are 

 observed, placed in a longitudinal row. The dactylus carries likewise a small conical 

 tooth, 1'5 mm. beyond that of the immobile finger, and between it and the articulatioa 

 five or six smaller teeth. The inner and the inferior sides of merus, carpus, and palm are 

 covered with slender spinules, those on each side are somewhat larger and arranged here 

 more or less distinctly in two longitudinal rows, four in all therefore, Ijut the upper and 

 outer sides are closely beset with much smaller spinules. 



The following legs are stout, a little hairy, and thickly covered, except on the lateral 

 parts, with minute spinules ; the legs are, however, partly broken and incomplete. The 

 propodites of the third pair reach almost to the end of the scaphocerites ; tlie carpus of 

 the following pair reaches to the cornea of the eyes, that of the fifth pair finally extends 

 to the anterior margin of tlie cephalothorax. The meropodites of the legs of the third 

 pair are 17 mm. long and 2"5 mm. thick in the middle. 



The cephalothorax of the female from the lliver Prah is smooth. The upper margin 

 of the rostrum (fig. 15) is straight till a little beyond the middle, then it curves very 

 slightly upwards, reaching to the end of the scales. It is armed above with 9 basal 

 teeth, the first two are on the carapace, the third just above its anterior margin, and the 

 ninth tooth reaches almost to the distal end of the j^edunclcs of the inner antennae ; 

 finally Avith two small apical teeth close to the tip, the posterior of which is separated by 

 a smooth interspace, which is 5 mm. long, from the foremost tooth of the basal portion. 

 The first and the second teeth are twice as distant from each other as the second is from 

 the third, and the three or four foremost teeth of the basal portion increase very slightly
