111. Chasmodes saburrae Sp. nov. P. (30824.) 



Allied to Chasmodes bosqui(()ius, but with the mouth smaller, the form 

 less elongate. 



Head 3i to Sf; depth 3i to Sf. D. XII, 17 ; A. II, 18. 



Body rather deep and compressed, less elongate than in Chosqulanus ; 

 the back somewhat arched. Head comparatively short, much shorter 

 than in C bosquianus, not one-fourth longer tlian deep; profile forming 

 a nearly even curve from the base of the dorsal to the tip of the snout, 

 which is not blunt, although less acute than in ot-her species of the 

 genus. 



Mouth low, nearly horizontal, the maxillary reaching to near the pos- 

 terior margin of the pupil, its length 2;^- to 2f in head (2 or less in C. 

 hosquianus), lower jaw included ; teeth rather short, equal ; toothless pos- 

 terior part of lower jaw occupying scarcely more than half the leugth 

 of its side; oblique length of snout 3i in head. Eye large, 5 in head, 

 half wider than the interorbital space. Lower edge of gill-oi)ening 

 opposite base of third ray of pectoral, the height of the slit 4^ to 5 in 

 head. Lateral line extending as far as tip of pectoral. A minute 

 cirrus (sometimes obsolete), not so long as pupil, above each eye, and a 

 similar one over each nostril. 



Dorsal fin continuous, the spines slender, but little lower than the 

 soft rays, the longest of the latter being li in head. Last ray of dorsal 

 joined to base of caudal; anal free from caudal. Caudal 1^ in head. 

 First two rays of anal short, in the males thickened and fleshy at tip, 

 the short anal papilla close in front of them. Pectorals a little shorter 

 than head; ventrals If in head. 



Females (in spirits) with about 8 irregular blackish cross-bars extend- 

 ing on the dorsal fin, everywhere freckled with pale spots; a bar below 

 eye, and two or three across the under side of head; fins all sharply 

 barred with blackish, in fine pattern ; the cross-bars on pectorals and 

 ventrals usually very distinct. 



Male in life: deep olivaceous, with traces of darker bjirs, and marbled 

 with light and dark; a series of round greenish spots along middle of 

 sides posteriorly, besides other series which form narrow undulating- 

 greenish lines converging backwards; a dark stripe downward and one 

 forward from eye; lower side of head mostly dusky. 



Dorsal fin dusky or greenish, the spinous part with a dark shade or 

 one or two dark blotches near the base, and with a median longitudinal
