412 M. A. Boeck on the Amphipoda 



name of Gammaropsis, of which those which have the hands 

 of the first pair larger than those of the second must belong 

 to the above-named genus ; but I think there is no reason for 

 referring them all here, as Bruzelius has done, and I will re- 

 tain the others under Lilljeborg's generic name. Bruzelius's 

 species A. punctata certainly coincides with Spence Bate's 

 Lonchomeres gracilis, which I have found at Farsund. The 

 species grandimana, established by Bruzelius, which was 

 found by Lilljeborg off the Swedish coast, I have also met 

 with at Farsund. 



AmpMthoe, Leach. — To this genus, from which all the spe- 

 cies have been removed which differ generically from the 

 typical species, rubricata, Mont., I can add a new Norwegian 

 species : — 



A. grandimana, mihi. — The body is somewhat compressed, 

 the epimera strongly ciliated on the lower margin ; the fifth is 

 the largest, oval, with a small emargination for the fifth pair 

 of legs in the upper posterior angle. The eyes are round and 

 black ; the superior antennae are longer than the inferior, with 

 about thirty joints in the flagellum. The palpi of the first 

 pair of maxillae are extremely long and slender, much longer 

 than the outer lamella. The first pair of feet are of moderate 

 size ; the fifth joint or hand is longer than the preceding joint; 

 the claws are strong. The second pair of hands in the females 

 are of about the same size and form as the first pair — in the 

 males, on the contrary, extremely large, longer than the pre- 

 ceding joints together, and oval. The finger is very large, 

 curved, and strong. The first joint in the third and fourth 

 pairs of legs is very strongly dilated, that of the following pair 

 is longer than broad. The animal, which was found at a 

 depth of a few fathoms at Farsund, was 6 millims. in length. 



Hela, mihi. — This remarkable new genus is characterized 

 by its long, slender, depressed body, small, nearly rudimentary 

 epimera, and very long legs, of which the first two pairs are 

 furnished with strong prehensile hands, the first ■ larger than 

 the second ; the last three pairs always have the first joint not 

 dilated, but narrow and cylindrical like the following joints, 

 and the claws are long and conical. The abdomen is of the 

 usual structure, and none of its segments are amalgamated. 

 The first three pairs of abdominal feet are exceedingly long 

 and thin, the two following pairs biramose, and the last pair 

 extremely thin, branched, with the branches longer than the 

 peduncle. The mandibles have a divided toothed apex, a pro- 

 minent masticatory tubercle, and a thin three-jointed palpus. 

 The palpi of the first pair of maxillae are long, thin, and two- 

 jointed ; the inner lamella is small, furnished with a few
