114 GAMMARID^. 



about tlie length of the peduncle ; the secondary ap- 

 pendage is short. The inferior antennae are very slight, 

 and nearly half as long again as the superior. The 

 epistoma is produced to a point. The first pair of 

 legs are long and slender ; the wrist and the hand are 

 nearly of the same length, the wrist being slightly the 

 longer of the two ; they have the inferior margin pa- 

 rallel with the superior ; the wrist is rather broader 

 than the hand, and has the inferior margin furnished 

 with a slight brush throughout its entire length ; the 

 hand has the inferior margin slightly waved; the palm 

 is oblique, and defined by a slightly obtuse angle, near 

 which stands one or two strong spines ; the palm is 

 also armed with three or four short spinules. The 

 finger is rather longer than the palm, but slightl}? 

 curved, increasing in diameter near the centre, where 

 it gradually tapers to a point, and is furnished Mitli 

 three small stiff spinules, which must add considerably 

 to the prehensile capability of the organ. The second 

 pair of legs are also very long, slender, and membran- 

 aceous ; the third joint is as long as the fourth ; the 

 wrist is half as long again as the hand, and furnished 

 U]ion the under-side, which is not at all jjrominent, with 

 a delicate fur of hair nearly throughout its entire length ; 

 the hand is long, pear-shaped, the broadest axis being 

 about one-third of its length from the apex ; the in- 

 ferior angle being produced ; the finger, which is very 

 minute, articulates posteriorly to the inferior angle, and 

 therefore the hand approaches somewhat to the form of 

 a double-fingered claw; the distal extremity of the 

 hand is covered with a fur of fine hairs. The walking- 

 legs are subequally long and slender, the three posterior 

 having the second joint developed to a broad scale, the 

 two last being produced a little downwards ; except the
