326 FISHES FROM BRAZIL JORDAN. 



preorbital, not placed so high as in Xyriclitliys novacula; preorbital 3^ 

 in head; depth of body, 3 in length; ventrals, 3 in body, produced in 

 long streamers which extend past first third of anal; dorsal and anal 

 each ending in a sharp point behind; caudal rounded, first two dorsal 

 spines a little shorter and a little less pungent than the rest, but very 

 similar to them; lateral line on second inll row of scales, U rows above 

 it, the half row forming the dorsal sheath; scales, 28. 



Color now faded, probably red, with blue spots on scales; a large 

 squarish silvery blotch on middle of side of body, as large as chiek 

 and preopercle; within this silvery area is a diamond-shape. I spot of jet 

 black, nearly covering a scale; sometimes a smaller spot below this. 

 Head with ten vertical bars of dark blue, the interspaces yellowish; a 

 j)ale streak along each side of snout, close to and parallel with edge of 

 profile; dorsal with cross-streaks of light blue; anal with blue, with 

 longitudinal streaks of paler and darker; caudal cross bai red with 

 darker; a few small scales below eye. 



A younger specimen is bluer and has the ventral streamers shorter: 

 little longer than head. 



A very young example has the ventrals extending little past front of 

 anal. In this the silvery area is obsolete, and the black lateral spot 

 very faint; no stripes on head. The first two dorsal spines are elevated 

 and flexible; caudal cross barred with dark; dorsal and anal with ob- 

 lique dark cross-streaks; back with very faint cross bars. This speci- 

 men approaches very closely to Xyrichthys rosipes from Key West, and 

 suggests that the types of this species must be the young of some ally 

 of Xyrichthys splemlena, possibly of Xyrichthys ventralis Bean. We tind 

 in tact no difference between A', rosipes and the young of X. splendens^ 

 except that in the former the first two dorsal spiues are a little higher 

 and the caudal fin not barred. 



89. Xyrichthys uniocellatus Agassiz. 



Form much as in .Y. novacula, the head sharp-edged, and the pre- 

 orbital very high. Eye 2^ in preorbital, which is 2^ in head; depth, 

 3^ in body. Ventrals, If in head, their filamentous tips reaching vent. 

 Soft dorsal and anal pointed behind ; dorsal spines pungent, the two 

 anterior shorter and not sharp. 



In alcohol very pale, perhaps once bright red; a blue vertical spot 

 on each scale; head with twelve blue bars. A black ink-like ocellus 

 bordered with bine at seventh dorsal spine ; a very obscure dusky 

 cross-band on body below it. Xo other marks evident. 



90. Sparisoma frondosum (Cuviei). (:' Sj)^-!!^ (Ustiiictus, circiimtwlatiis and emargi- 



vahis Poey.) 



One adult; one young specimen, probably belonging to the species 

 called frondosum by Cnvier, Agassiz. and Giinther. Three of the nom- 

 inal species of Poey may belong here.
