larities. In A. calif oniica the stout notopodial setae were said to be 

 almost completely concealed in the felt. This character, in itself, is not 

 significant for it is sometimes dependent on the amount of accumulated 

 debris or attached organisms rather than on an actual difference in 

 the lengths of these setae. Fauvel (1925, p. 140) questionably referred 

 A. castanea Moore and A. longipalpa Essenberg (1917, p. 403) to A. 

 talpa Quatrefages (1865, p. 196) from Australia. This identity seems 

 extremely unlikely, especially because of the differences in the setae of 

 both notopodia and neuropodia. Unless a restudy of the type of A. 

 longipalpa is possible, this name is perhaps to be considered a doubtful 

 one. There is no convincing record that A. talpa Quatrefages occurs in 

 the eastern Pacific. Also, none of the specimens here available from the 

 eastern Pacific have neuropodial setae as shown by Fauvel (1925, fig. 

 4) who re-examined the type specimen of A. talpa and made a careful 

 study of the setae. 



A. defendens Chamberlin (1919a, p. 80) was described from Peru, 

 in 1,036 fms. The great depth from which it was taken does not favor 

 its comparison with species from shallower waters without additional 

 collections from similar depths. 



The following species of APHRODITIDAE are taken up in this 

 report. 



Aphrodita armifera Moore (includes A. raripillata Essenberg) 

 Aphrodita japonica Marenzeller (includes A. cryptommata Essenberg

Aphrodita refulgida Moore (includes A. solitaria Essenberg) 

 Aphrodita falcifera, new species 

 Pontogenia laeviseta, new species
