Fleros {Cichlasoma) octofasciatus. 



Heros octofasciattis, Began, Revue Suisse Zool. xi. 1903, p. 417, pi. xiii, 

 fig-1. 



Depth of body 2-2| times in the total length, length of 

 head 2|-3 times. Snout nearly as long as or a little longer 

 than the eye, the diameter of which is 3^—4^ times in the 

 length of head, interorbital width about 3 times. Maxillary 

 extending to vertical from anterior margin of eye ; breadth 

 of prseorbital \~^ diameter of eye ; cheek with 5 or 6 series 

 of scales ; fold of lower lip interrupted in the middle. Sc. 

 28-31 ll^. 3|-4 scales between the upper lateral line and 

 the scaly sheath at the base of the soft dorsal. D. XVII- 

 XIX 8-10. A, VII I-X 7-8. Dorsal commencing above 

 or a little before the axil of pectoral, the spines increasing in 

 length to the sixth or seventh, which is 2§-3^ times in the 

 length of head, thence subequal ; soft dorsal and anal pointed; 

 pectoral |-4 length of head ; ventrals extending to the base 

 of fourth or tifth anal spine ; caudal rounded ; caudal peduncle 

 l|-2j times as long as deep. In tlie young dark cross-bands 

 on the body, which become indistinct in the adult; a dark 

 blotch on the middle of the side below the lateral line and 

 another on the upper half of the base of the caudal, this latter 

 often ocellated; in the adult a dark band running from the 

 eye to the blotch on the side ; usually some light blue spots 

 on the head and one on each scale of the side of the body ; 

 vertical fins with small dark spots. 



Total length 130 mm. 



Several examples from British Honduras, collected by the 

 Rev. J. Robertson. 



I am glad to be able to give a more complete account of 

 this species, which was originally described from a little 

 example of 50 mm. It is closely allied to //. multispinosus, 

 Gthr., which has much stronger and longer dorsal spines, 

 and to H. nigrofasciatus, Gthr., which has a broader pra;- 

 orbital and only 2^ scales between the upper lateral line and 

 the sheath at the base of the soft dorsal fin. 



Heros {Heros) callolepis^ sp. n. 



Depth of body a,bout 2f times in the total length, length 

 of head 3 times. Eye nearer to posterior edge of operculum 

 tlian to end of snout, its diameter 3^ times in the length of 

 head and equal to the interorbital width. Maxillary not 

 extending to below the eye; breadth of preeorbital equal to 

 the diameter of eye ; cheek with 4 or 5 series of scales ; lower
