502 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 
XVIII, PARAPRISTIPOMA. 
Parapristipoma Bleeker, Archives Néerlandaises, VIII, 1872 (trilineatum). 
Type: Perca trilineata Thunberg, from Japan. 
Ktymology: zapd, near; Pristipoma; the genus being intermediate 
between Pomadasis and Pleetorhynechus. 
We follow Bleeker in referring to this genus the species viridense 
(octolineatum), whichis certainly very closely allied to Parapristipoma 
trilineatum. Along with this we place the second European species, 
mediterraneum, which, although having something in common with the 
type of Plectorhynchus, is nearer Parapristipoma than to Plectorhynchus 
cheetodonoides. The genus called Plectorhynchus (= Diagramma Cuvier) 
contains some 40 species, all confined to the eastern Pacific and the 
Indian Ocean. The species of Parapristipoma have comparatively long 
and slender gill-rakers, a character overlooked by Bleeker. The exten- 
sion of the scales at the bases of dorsal and anal is also characteristic, 
as is also the scaliness of the lower jaw and suborbital bones. As this 
genus has received little attention, we give the following: 
ANALYSIS OF EUROPEAN SPECIES OF PARAPRISTIPOMA, 
a. Dorsal fin low and nearly continuous; anal short and high; dorsal and anal both 
with a scaly sheath at base; caudal fin lunate; gill-rakers long and slender; 
scales small. 
b. Soft dorsal nearly as long as spinous part; dorsal spines twelve; lower jaw 
included. Body elliptical, stout, dorsal and ventral outlines nearly straight, 
anterior profile steep and straightish, much convex at nape; snout long and 
sharp; teeth arranged in broad bands, the outer above scarcely enlarged; eye 
large; preopercle sharply serrate; gill-rakers long and slender, x21; scales 
small, about 64 pores in the lateral line; soft dorsal and anal scaled at base; 
dorsal fin low, fifth and sixth spines longest, the others subequal; anal deeply 
sheathed, soft part high and pointed, the second spine long and slender, not 
quite equal to third; pectoral pointed; caudal shallow-forked. Color, grayish 
brown, with two or three faint longitudinai lines along the sides; edge of 
fins dusky. Head, 34; depth, 2?; D. xu, 17; A. 111, 8 to 10; eye, 34; snout, 3; 
maxillary, 3}; pectoral, 1}; fifth dorsal spine, 23; second anal spine, 2%; soft 
dorsal, 1, in spinous. Scales, 65-70.........-..:....-. MEDITERRANEUM, 86, 
bb. (Soft dorsal about two-thirds length of spinous part; dorsal spines 13; pee- 
toral fin short, 14 in head; lower jaw projecting. Body rather stout, the back 
moderately elevated, the depth about equal to length of head, 3 in body; 
mouth moderate, the maxillary reaching past front of eye; eye, 3} in head, the 
eye much wider than the narrow preorbital and lower than snout; dorsal fin 
continuous, thespines rather low and slender; second anal spine rather long 
and strong; about equal to third and rather shorter than the soft rays; pre- 
opercle sharply serrate; soft dorsal and anal scaly; D. xi, 14; A. Im, 7; 
scales small, 12-57-23. Coloration olivaceous, with four narrow sky-blue 
longitudinal streaks on cach side of back, the lowest and broadest at level of 
eye; traces of a fifth streak on cheek; fins blotched with dark. Sometimes 
nearly plain olivaceous, with the fins dark-edged.) (Steindachner.)
