Heros (Cichlasoma) octofasciatus. 



Heros octofasciatus, Regan, 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 prgeorbital g-f diameter of eye ; cheek with 5 or 6 series 

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

 28-31 jH|. 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. VIII-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 |-f length of head ; ventrals extending to the base 

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

 lf-2£ times as long as deep. In the 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 H. 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 about 2| times in the total length, length 

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

 than 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 prseorbital equal to 

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