270 On the Classification of Teleostean Fishes. 
(12-144 14-20) they approach Oollichthys (11418) and 
Lonchurus(10+19). Ithereforeaccept the family Sillaginide 
of Richardson as defined by Gill and by Bleeker. 
The oblong and elongated cavernous head, with the pre- 
opercle bent inwards below, covering a considerable part of 
the lower surface of the head, recalls Aspro among the 
Percide, with which genus Sillago has been associated by 
Bleeker in 1859. 
4, The Pseudochromidide of J. Miller and of Bleeker 
(partim), including the Malacanthidee of Giinther, the Latilide 
and Opisthognathide of Gill, the Bathymasteridee of Jordan, 
are Perciformes closely related to the Serranide and connected 
with them through Plesiops and allies. The ventrals are 
truly thoracic, the pelvis being in every way similar to that 
of the Perches ; they are, however, sometimes a little anterior 
to the insertion of the pectorals, just as in Centropristes among 
the Serranide and Xyrichthys among the Labride, and such 
a position has been described as ‘“subjugular.’’? Second 
suborbital with an internal lamina; entopterygoid present ; 
post-temporal forked; anterior vertebra without transverse 
processes ; ribs inserted on the transverse processes where 
these are developed ; epipleurals inserted at base of ribs ; 
dorsal and anal fins elongate and formed mostly of articulated 
soft rays.
