the excavate setulose inner border of the small obtuse finger. Still 

 less apparently can there be any gi-asping power between the blunt 

 apex of the sixth joint and the stumpy pyramidal finger in the fifth 

 perseopods. 



The first and second pairs of pleopods in the male are sym- 

 metrical, the second much wider apart than the first, and both 

 differing from those figured for P. pilosimanus in being apically 

 broader. The distal part of the second pair is beset with more 

 or less curving spines. 



The left uropod is very much larger than the right. The telson is 

 nearly symmetrical, its arcuate distal margin having four widely 

 spaced spines on the left, and five nearer together on the left. The 

 pleon is unusually small in comparison with the fore part of the 

 animal. The female specimen, considerably smaller than the male 

 has its pleon encased in an Epizoanthus colony. 



Both specimens have bladder-like organisms attached to the bases 

 of some of their appendages. These additions to the animal's 

 economy seem to be unusual. 



The specimens, No. 153, were obtained by Dr. Gilchrist, Buffalo 

 Eiver, N.W. | W. 19 miles, from 549 m. depth. 



The specific name is given out of respect to Prof. E, L. Bouvier,

 " Simon's Bay, 18 fathoms [33 m.] . A male specimen, in 

 a shell of Trochits benzi, Krauss. It is with some hesitation 

 that this is referred to the present species, and subsequent 

 investigation may show it to be distinct. The chelipedes and 

 ambulatory limbs are more hairy, and the dactyli of the latter 

 are ciliated and slightly longer on the right side ; the hand of 

 the right chelipede is more strongly granulated, and a distinct 

 finely tubercular line is present near the outer border. In 

 other respects it agrees with Anapagurus pusillus."
