ON FISHES FROM THE PERSIAN GULF. 319 



prseorbital a little deeper than long. Dorsal 14 ; anal 15 ; both scaly 



and commencing nearly opposite each other ; pectoral as long as 

 distance from posterior margin of operculum to anterior edge of pupil ; 

 origin of ventrals equidistant from anterior edge of praeoperculum and 

 base of caudal ; caudal forked. Scales deciduous, 50-55 in a longi- 

 tudinal series. A silvery stripe on the side becoming broader 

 posteriorly. 



Length, to base of caudal, 188 mm. 



A single specimen from Karachi. 



APOGON HOLOTjENIA. 



Depth of body nearly oqual to length of head, 2f times in the length 

 (without caudal). Snout § as long as eye, the diameter of which is 2| 

 times in the length of head, interorbital width about 5 times. Lower 

 jaw slightly projecting ; maxillary extending to below posterior edge of 

 pupil. Outer edge of prseopercle, suborbital ring and supraclavicle 

 finely serrated. Dorsal VII, I 9. Anal II 8. Second dorsal spine 

 ?-4 the length of third, which is stronger and slightly longer than the 

 fourth and equal to \ the length of head ; second anal spine -3- the length 

 of head ; soft dorsal and anal with outer edges emarginate ; pectoral 

 extending slightly beyond, ventral nearly to origin of anal ; caudal 

 notched, with rounded lobes. 25-26 scales in a longitudinal series. 

 Caudal peduncle I2 times as long as deep. Head and body with longi- 

 tudinal black stripes ; a median one from between the eyes nearly to 

 origin of spinous dorsal ; on each side one from the snout, running- 

 above the eye and the lateral line to the caudal peduncle ; a second from 

 the upper part of eye running below the lateral line to below the soft 

 dorsal ; a third from tip of snout through the eye and along the middle 

 of the side to the extremity of the caudal ; a fourth from tip of lower 

 jaw through the base of pectoral to the caudal peduncle; faint traces of 

 a dusky stripe at the base of both soft dorsal and anal. 



Length, to base of caudal, 44 mm. 



Three specimens from Muscat, 15-30 fathoms. 



This is the species figured by Day* as A. endekatcenia (Blkr.) and which 

 Bleekor considered to be identical with A. fasciatus (White). Several 

 species have been confounded under this latter name, which differ from 

 each other not only in form and proportions, but also constantly in the
