Not included in the key are A. kergueleni Stebbing (1888), a female, 

 but see Chevreux (1927) for a possibly correct assignment of a male; 

 A. megalojproto'pus Stebbing (1895), which probably belongs in the 

 genus Exampithoe because of its enlarged first gnathopod. 



Notes on the Literature of Ampithoe 



The genus Ampithoe and many of its species are nomenclaturally 

 quite old. Several species have been based on females or juveniles, 

 and this early confusion still has not been straightened out. 



The most important and involved situation is that concerning 

 Ampithoe femorata Kr0yer and A. brevipes Dana. Stebbing (1906), 

 without new material, recognized both species but noted their close 

 afiinities. By evidence of his synonymies, he considered A. gaudi- 

 chaudii Milne Edwards a senior synonym of A. femorata, and he in- 

 cluded questionably in A. brevipes the species A. peregrina Dana and 

 A.jalklandi Bate. These species are scattered widely in the Southern 

 Hemisphere on both sides of South America. Chilton (1921) also 

 reported A. femorata from the Juan Fernandez Islands. 



Schellenberg (1931) combined femorata and brevipes and their 

 synonyms, including K. H. Barnard's (1916) reference to brevipes. 

 K. H. Barnard (1932) gave a new name, falsa, to his 1916 brevipes 

 identification from South Africa, but reported on brevipes from the 

 Falkland Islands and mentioned A. chilensis as a possible synonym. 

 Stephensen (1949) reported brevipes from Tristan da Cunha (again) 

 noting the characteristic swelling of article 4 of pereopods 1-2. J. L. 

 Barnard (1952) erroneously identified femorata from California. In 

 retrospect, I relied upon Bate's (1862) figure of brevipes (pi. 43, fig. 2) 

 showing the short flagellum of antenna 2. My identification should be 

 referred to A. lindbergi. The early drawings and descriptions of 

 brevipes, falklandi, peregrina, gaudichaudii, and chilensis leave much 

 to be desired in comparison to the better described A. femorata. The 

 gnathopods of the supposedly iemsde falklandi are rather stouter than 

 expected for brevipes, and the fifth article has a posterior lobe. I 

 strongly question that falklandi is a synonym of brevipes, as figured in 

 the literature, although, falklandi seems to fit brevipes as to be expected 

 of a female. There are discrepancies in the stoutness of article 4 of 

 pereopods 1-2 in the various figures of Bate (1862). Considering the 

 situation in California of several Ampithoes such as humeralis, lindbergi 

 mea, tea, and plea, all very diSicult to separate in female, juvenile, and
