REPORT ON THE AMPHIPODA. 



1315 



Locality. — Station 50, off Nova Scotia; lat. 42° 8' N., long. 63° 39' W.; depth, 

 1250fathoms. 



Remarks. — The name is given in honour of the deceased naturalist, v. Willemoes 

 Suhm, who during the voyage made the rough sketch, here reproduced, of this interesting 

 animal. The drawing is said to be magnified to double the size of the specimen, but 

 seems to be rather in excess of that. The species appears to come near to Lanceola

serrata, Bovallius, " from the mouth of Davis Strait," but in that species the pleon is 

 said to be shorter than half the perseon with the head, and the segments of the peraeon 

 are said to be smooth, only the segments of the pleon being mentioned as forming a 

 serrated keel. 



Lanceola australis, n. sp. 



Head forming an obtuse angle in front, without rostrum ; the whole dorsal line of 

 the animal angled ; the seventh segment of the perseon has the dorsal line produced 

 backwards in a very small tooth ; each of the first three segments of the pleon has a 

 similar but rather larger tooth. 



Eyes very small, projecting a little from the surface of the head. 



Upjier Antennae as in Lanceola asstiva, but with the large flagellum joint more 

 strongly curved. 



Lower Antennas similar to those of Lanceola asstiva, but showing no minute apical 

 joints. 



Mandibles not very different from those of Lanceola asstiva ; the tooth on the lower 

 margin behind the cutting edge very minute ; the inner groove or ridge extending with 

 sinuous outline from the rear of the cutting plates for almost the whole length of the 

 trunk ; the second joint of the palp without setse at the distal end, not very much longer 

 than the third joint.
