PANTHALIS EVANIDA (Treadwell), new combination 



Eupanthalis evanida Tkeadweix, 1926, p. 186 (U.S.N.M. no. 19208, Philippine 

 Islands). 



This species has globular ommatophores as characteristic of the 

 genus Panthalis. Parapodial glands are present from the eighth

This was originally described as a polynoid, but the type has the 

 characteristic features of the genus Hermione^ of the family Aphro- 

 ditidae. It is colorless except for the pale amber, stout spines. 

 There are 15 pairs of soft, imbricated scales ; ventral setae are distally 

 falcate, laterally with a few stout teeth ; notopodial setae include some 

 barbed, arrow-headed. The prostomium has a single median antenna 

 and a pair of anterior peduncled eyes. These are indicated in the 

 original figure as the bases of a pair of lateral tentacles.
