lower lateral line, which extends forward to or nearly to pectoral fin. Dorsal IX-X 

 26-29. Anal 26-30. Pectoral f to nearly f length of head, much longer than the pelvics, 

 which do not nearly reach the vent. Caudal truncate or a little emarginate; caudal

This species was previously unrepresented in the British Museum collection. I have
