Depth of body 2| to 2| in the total length ; width of inter- 

 orbital region 2| to 2| in the length of the head ; vertical limb 

 of preopercle denticulated throughout its entire length • fifth 

 dorsal spine 2J in the head; last dorsal spine much shorter than 

 the fifth; third anal spine a little longer than the second, If to 

 1§ in tlie longest ray; ventral not reaching to the vent ; pectoral 

 equal to the ventral ; upper surface of the head conspicuously 

 rugose. 



Length 270 millimeters ... ... ... ... liaswellii. 



Of course the disparity in the size of the specimens must be 

 taken into consideration, but even giving this its full value some 

 of the differences, such as that between the width of the inter- 

 orbital region in the two forms, are quite abnormal. 



3. Carassiops ouentheki. 



Eight examples, the largest 90 millimeters. I have already 

 (p. 787) given my reasons for removing this handsome species 

 from the genus Asterropteryx to which it had been ascribed by 

 Bleeker. 



■i. ? OpHIOCARA APOliOS. 



Two specimens, the largest 144 millimetres. 



5. Eleotris fuscus. 



The bulk of the collection belongs to this species, of which 



examples measuring 166 millimeters were brought back by Mr. 



Hedley. 



6. Trichopharvnx chassilabris. 



Gobius crassilahris, Giinther, Catal. Fish. iii. p. 63, 1861. 

 Three specimens, the largest 122 millimetres. 

 I have found it necessary to establish a new genus for this 

 handsome Goby, as follows : — 



Trichopharyxx, gen.nov. 



Gobius sp., Giinther, Catal. Fish. iii. p. 63, 1861. 



Body robust, cylindrical in front, compressed behind. Head 

 large, wider than deep, with long rounded snout. Mouth wide, 

 with short, nearly horizontal cleft, the lips thick and folded
