52. Apogon quinquestriatus, sp. n. 
Depth of body 3 in the length, length of head 2%. Snout 2 as long as eye, the 
diameter of which is 3 in the length of head; interorbital width 4 in the length of head. 
Jaws equal anteriorly ; maxillary extending to below middle of eye. Praeoperculum 
serrated ; praeopercular ridge and supraclavicle entire. 13 or 14 gill-rakers on the 
lower part of anterior arch. About 24 scales in a longitudinal series. Dorsal VII, 19; 
spines rather slender, the third the longest and 4 the length of head ; soft dorsal highest 
anteriorly, the free edge probably slightly concave. Anal II 8, the second spine 4 the 
length of head. Pectoral $ the length of head; ventrals nearly reaching the origin 
of anal. Caudal probably notched. Caudal peduncle 14 as long as deep. A dark 
longitudinal stripe from the snout through the eye to the end of the middle caudal rays, 
another from above the eye to the upper part of the caudal peduncle; a median stripe 
from interorbital region to origin of dorsal. 
Maldives, 8. Nilandu, 30 to 36 fathoms. 
Two specimens, 46 mm. in total length. 
Allied to 4. quadrifasciatus, C. & V., and to A. septemstriatus, Gthr. 
538. Apogon teniophorus, sp. n. 
Depth of body 2? to 3 in the length, length of head 2. Snout 3 to ? as long as eye, 
the diameter of which is 2? to 3} in the length of head; interorbital width 43 to 5 in 
the length of head. Jaws equal anteriorly; maxillary extending to below the posterior 
edge of pupil, or a little beyond. Preeoperculum serrated ; preeopercular ridge and sub- 
orbitals entire; supraclavicle denticulated. 12 gill-rakers on the lower -part of the 
anterior arch. 24 scales in a longitudinal series. Dorsal VII, 1 9; third spine longest 
and strongest, $ to 3 the length of head; soft dorsal higher than the spinous, the 
anterior rays the longest, the free edge concave. Anal II 8, the second spine 4 to 2 the 
length of head. Pectoral 3 to 2 the length of head; ventrals extending to the origin of 
anal. Caudal notched. Caudal peduncle 13 to 12 as long as deep. 4 dark longi- 
tudinal stripes on each side, the uppermost at the base of the dorsal fins, the others 
terminating on the basal part of the caudal; second stripe originating on the snout and 
running above the eye and the lateral line; third stripe running from the snout through 
the eye and the base of the pectoral along the middle of the side, not expanding to form 
a spot on the caudal peduncle; fourth stripe originating at the lower part of the eye; 
on the opercular bones the third and fourth stripes are somewhat expanded and very 
strongly defined; a dark stripe on the basal part of the soft dorsal, a less distinct one ~ 
on the anal. 
Maldives. 
Three specimens, the largest 92 mm. in total length. 
The species is nearest to 4. balinensis, Blky. A specimen from Samoa has recently 
been figured by Jordan and Seale (Bull. U.S. Fish. Bureau, xxv. 1905, fig. 37) as a 
colour-variety of A. novemfasciatus, C. & V.
