REPORT ON THE AMPHIPODA. 1061 



the cleft spines four in number on the second and third pairs ; the joints of the rami 

 numbering from sixteen to eighteen. 



Uropods. — The peduncles of the first pair subequal in length to the rami ; the rami 

 almost equal, with few marginal spines, the upper edges pectinate ; the peduncles of the 

 second pair scarcely reaching beyond those of the first pair, longer than the outer ramus, 

 subequal in length to the inner ; both rami have strongly pectinate edges, the upper 

 and longer ramus having also five spines on one margin and one at the top of the other, 

 the lower ramus having three spines on one margin and two near the top of the other ; 

 the peduncles of the third pair shorter than the rami, having two spines on the upper 

 inner margin ; the rami broad, lanceolate, the outer the narrower, not longer than the 

 inner, but produced beyond it, with six or seven small spines along the outer margin, 

 the inner margin serrate, pectinate, carrying nine or ten plumose setae ; the inner rami 

 coming together like the plates of a cleft telson, the inner margin smooth, the outer 

 serrate, furnished with spines and plumose setse, few of which, however, were remaining 

 in our specimen. 



The Telson not twice as long as broad, widest at a little distance from the base, the 

 convex sides then rapidly converging to the two acute apices, being notched for a spine 

 a little before the apex is reached ; cleft between four-fifths and three-quarters of the 

 length, not dehiscent ; the surface has a couple of spines not symmetrically placed, one 

 on either side of the cleft. 



Length. — The specimen, in the position figured, measured, in a straight line from the 

 front of the head to the apex of the third uropods, just over a fifth of an inch. 



Locality. — The single specimen was labelled as having been taken at the surface on 

 February 18, 1875, off Samboangan, Philippine Islands. 



Remarks. — The specific name refers to the place of capture. 



From the other species here described the present is rather remarkably distinguished 

 by the long fifth joint of the upper antennae, and the great palp of the mandibles, but 

 these differences do not seem to require the institution of a new genus. 



Family Photida 



In 1870 Boeck made the Photinse the eighteenth subfamily of the Gammaridse ; by 

 a misreckoning in the Crust, amph. bor. et arct., p. 151, he calls it " Subfamilia xvn.," 

 and from the account which he gives of his earlier work in his later, De Skand. og 

 Arkt. Amphipoder, p. 72, he omits the Photinse altogether, perhaps owing to the 

 previous miscalculation. In the later work itself he makes the Photinse the second 

 subfamily of a new family, the Photidse, in which he also places the Leptocheirinas and
