PSEUDOSCARUS XANTHOPLEURA Sleeker. 



This East Indian species is reported by Fowler from Honolulu. 

 Fowler regards it as distinct from P. heliotropinus Bryan, which it 

 certainly resembles. 



Family ECHENEIDAE 



Genus REMOROPSIS Gill 



KEMOROPSIS BRACK YPTERA (Lowe). 



Reported by Fowler. 



Family GOBIIDAE 



OPUA E. K. Jordan, new genus 



(Type. — Opua nephodes E. K. Jordan.) 



This genus, with Mugilogohius and Vaimosa, differs from other 

 genera of Gohiidae in having scales on the upper part of the opercle, 

 but none on the cheeks. From Vaimosa and Mugilogohius it is dis- 

 tinguished by the larger scales, which do not decrease in size an- 

 teriorly; by the larger teeth in several series, with two moderate 

 canines in the middle of the side of the lower jaw, and by the shape 

 of the head, the interorbital being much narrower and not flattened 

 above. The dorsal spines are not prolonged into filaments as in 

 Mugilogohius.
