REPORT ON THE AMPHIPODA. 1087 



long and setiform ; the longer ramus has three spines on the outer and four on the inner 

 margin, and half a dozen setiform spines at the rounded apex ; of these rami, it is the 

 outer apparently that is the shorter, not the inner as would be recpuired by Boeck's 

 account of this genus. 



Telson not reaching beyond the peduncles of the third uropods, scarcely longer than 

 broad, the apical margin forming three points, of which the central is a little the most 

 produced ; at each outer corner there is a cilium, and along the raised line which runs 

 obliquely from each corner upon the upper surface there are on each side five setiform 

 spines. 



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

 front of the head to the extremity of the uropods, nine-twentieths of an inch. 



Locality. — Station 162, off East Moncceur Island, Bass Strait, April 2, 1874; depth, 

 38 fathoms ; bottom, sand and shells. One specimen. 



Remarks. — The specific name, from the Greek ^iXew, I love, and anavOa, a spine, 

 seems justified by the bush of spines on the mandibular palp and the row of spines on the 

 lower lip, as well as the more usual spininess of the gnathopods. 



The species has much resemblance to Autonoe plumosa, Boeck, from which, however, 

 the antennae and first gnathopods separate it, and likewise to Microdeutopus australis, 

 Haswell, from Port Jackson, which is likewise an Autonoe, but distinguished from the 

 present species by having the third joint of the peduncle of the upper antennae " very 

 short," by the first gnathopods, in which the wrist is described and figured as being 

 larger than the hand, by having " second pair of pereiopoda longer than the first ; 

 dactylos in both long, slender," and lastly by having the rami of the third uropods 

 " lanceolate." 



Autonoe kergueleni, n. sp. (PL CXI.). 



Rostrum small, lateral lobes of the head small, acute ; in the first three pleon- 

 segments the lower lobe of the hind margin taking the place of the postero-lateral angles, 

 the separation between the lobe and the true lower margin being marked by a minute 

 notch and setule ; the third pleon-segment is longer than either of the two preceding 

 segments ; the fourth segment has a transverse dorsal depression. 



Eyes small, situated on the lateral lobes of the head. 



Upper Antennse. — The first joint large, longer than the head, with some spiuules 

 and spines, chiefly on the under margin. The remainder of these antennas broken off. 



Lower Antennae. — The first two joints short, the gland-cone small, acute, decurrent ; 

 the third joint broad, not twice as long as broad, armed with some slender spines ; the 

 fourth and fifth joints long, subequal in length, the fifth the thinner, both equipped with
