REPORT ON THE ANOMURA. 15 



anterior end. The propodus presents a sinuous outline, and is about twice the length of 

 the carpus ; a small tubercle exists on its distal end opposite the upper of the two carpal 

 spines, the superior surface is slightly hollowed out, and two tubercular elevations are 

 placed over the insertion of the dactylus. The dactylus is acute, and both it and the 

 immobile finger are sparingly toothed, and possess smooth polished tips. The first and 

 second pairs of ambulatory limbs are subequal, and in addition to the ordinary brownish 

 pubescence possess stiff hairs on their margins. The carpal joints are dilated, and the 

 upper surface is divided by a longitudinal ridge into anterior and posterior parts ; the 

 dactyli are long, and each ends in a yellow claw, a few short yellowish spines also exist 

 on the inferior border. The third and fourth ambulatory limbs are remarkably small 

 and subequal in size, the proportions of the joints being somewhat similar in both. The 

 dactylus is short and curved, and in each case lies between two claw-like prolongations of 

 the propodus ; one of these is, however, poorly developed in the third pair. The coxae of 

 all the ambulatory legs are fringed with long hairs. 



The abdomen in the female is broad and rounded, each segment (except the first) 

 possessing a median elevation, and on either side of this a small projection on the anterior 

 edge which overlaps the preceding segment. In the male the seventh segment ends in a 

 pointed spine. The sternal sulci of the female are deeply furrowed, each commences 

 opposite the third pair of ambulatory limbs, and, passing forwards as far as the 

 posterior border of the chelipedal segment, ends by joining its fellow in a raised 

 tubercle which passes some short distance backwards in the middle line. Six pairs of 

 abdominal appendages are present in the female, the ultimate pair being of small size. 

 The male sexual appendages are well developed, especially those of the first pair. 



The larger (female) specimen gives the following measurements : breadth of carapace 

 11 '7 mm., length of carapace 15 mm., of chelipede 20 mm., and of first ambulatory leg 

 19*5 mm. 



The peculiarly bilobed frontal region, and the small size of the two last pairs of 

 legs (characters which I regard as of gelieric importance), at once distinguish this species 

 from all other known Dromiids. 



Habitat. — Station 142, oW the Agulhas Bank ; depth, 150 fathoms; bottom, green 

 sand. Two specimens (male and female). The female has several Foraminifera attached 

 to its carapace and limbs. Dromidia hicornis, Studer, was taken in the same locality. 



Genus Pseudodromia, Stimpson.

Carapace elongated, convex, pubescent. Facial region considerably broader than
