ON FISHES FROM THE PERSIAN GULF. 321 



lower jaw to the anal ; a blackish stripe on the basal part of both soft 

 dorsal and anal fins. 



Length, to base of caudal. 73 mm. 



Nine specimens, from Charbar, Mekran Coast, from Karachi, from 

 the Nicobars (Day Coll.) and from Zanzibar (Playfair Coll.) This species 

 is closely allied to A. fasciatus (White) and A. endekatcenia. (Blkr.), 

 differing from both in the arrangement of the stripes, the wider 

 interorbital space and the included lower jaw. 



Apogon spilurtjs (PI. Ill, fig. 5). 

 Depth of body about 2f times in the length (without caudal), length 

 of head 2|-2| times. Snout shorter than eye, the diameter of which 

 is 2f times in the length of head and greater than the interorbital width. 

 Maxillary extending to below posterior edge of pupil ; lower jaw scarcely 

 projecting. Outer edge of prseoperculum serrated ; other bones of the 

 head entire. Dorsal VII, I 9. Anal II 8. Dorsal spines rather slen- 

 der, the second about half as long us the third, which is somewhat 

 stronger but not longer than the fourth ; longest dorsal spine about 

 | the length of head ; second anal spine 5-5 the length of head ; soft 

 dorsal and anal with their outer edges emarginate ; pectoral extending 

 a little beyond, ventral nearly to origin of anal ; caudal notched, with 

 rounded lobes. 26 scales in a longitudinal series. Caudal peduncle 

 lg-H times as long as deep. A blackish longitudinal stripe from the 

 snout through the eye to the edge of the prseoperculum ; a blackish 

 spot on each side at the base of the caudal, usually above the lateral 

 line and sometimes confluent dorsally with its fellow ; a blackish stripe 

 along the base of the anal. 



Length, to base of caudal, 50 mm. 

 Five specimens from Karachi. 



This species bears a considerable resemblance to the Japanese 

 A. notatus, which is at once distinguished by the strongly projecting 

 lower jaw. 



Apogonichthys nudus (PI. Ill, fig. 6). 

 Depth of body about 3§ times in the length (without caudal), length 

 of head nearly 3 times. Snout shorter than the diameter of eye, which 

 is ^ the length of head and greater than the interorbital width. Cleft 

 of mouth very oblique, the maxillary extending to below the anterior 

 \ of eye, the lower jaw projecting. None of the hones of the head 

 serrated ; praeoperculum with posterior edge slightly emarginate and
