REPORT ON THE AMPHIPODA. 1057 



surface carrying on each side half a dozen or more setse, not quite symmetrically 

 arranged. 



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, rather over half an inch. Fully 

 extended it would have measured a cood deal more. 



Locality.— Station 142, off Cape Agulhas, December 18, 1873; lat. 35° 4' S., long, 

 18° 37' E. ; depth, 150 fathoms; bottom, green sand; bottom temperature, 47°. 

 Three specimens. 



Remarks. — The specific name refers to the colour of the specimens in spirits, which 

 were dark, the branchial vesicles in particular being port-wine coloured. 



Ampelisca zamboangse, n. sp. (PI. CVL). 



Tfie Head as in Ampelisca fusca ; the body more or less acutely compressed ; the 

 postero-lateral corners of the third pleon-segment almost right-angled, but with the points 

 rounded ; the fourth segment with a transverse dorsal depression, the carina at its apex 

 raised above the succeeding segment ; the fifth and sixth segments almost completely 

 fused, the division marked by a transverse dorsal depression, the sixth segment with the 

 usual dorsal and lower angles. 



The Eyes small, the two pairs situated as in Ampelisca fusca. 



Upper Antennse. — First joint short and broad, with some feathered cilia on the upper 

 margin, some groups of spines on the surface and at the apex, the lower surface adorned 

 with seven or eight rows of long fine hairs ; the second joint much narrower but not 

 longer than the first, very much shorter than the head, furnished below with eight or 

 nine groups of hairs like those of the first joint, but shorter ; the third joint short, rather 

 longer than broad ; the fiagellum of about twenty-four joints, together much longer than 

 the peduncle, the first tapering, its upper margin straight, the lower oblique, armed with 

 five groups of long and broad cylinders ; on the third joint there is also a cylinder ; the 

 terminal joints are very long and slender. 



Lower Antennse much longer than the upper. The first two joints short; what appears 

 to be the gland-cone of the second very inconspicuous ; an acute apex on the opposite 

 side ; the third joint scarcely longer than broad, the serrate lower (or ? inner) margin 

 closely set with nine or ten brushes of long hairs like those of the upper antennse ; the 

 fourth joint nearly as long as the first and second of the upper antennse united, with 

 a few spines on the upper margin and thirteen tufts of hairs on the serrate lower margin ; 

 the fifth joint much longer, very slender, the spinules more thickly set on the lower than 

 the upper margin ; fiagellum much longer than the peduncle, also much longer than the
