depth 2 (2| in total), D. XII, 14; A. II, 12 ; Scales 3—28- 10. Length 4 

 inches. 



This species is ai)pareutly closely related to P. fusciis Castelnau and 

 to P. atrocyaneus Poey ; the latter species is said to have the depth 3 in 

 total length, while the former is described as having the preorbital and 

 preopercle weakly serrate, and a black blotch on the back of the tail.

Common about rocks and in tide-pools. 



LABRIDiE. 



128. Lachnolaenius suillus Cuvier. Hog-fish. 



{Lachnolwmus falcatus Cuv. & Val., not Labrus falcatus L.) 



A common food-fish, reaching a weight of six or eight pounds. The 

 flesh is white and considered good, although less valued at Key We'st 

 than in some other regions. 



The variations in the ground color are considerable, older fishes and 

 fishes taken in deep water being much redder than small fishes or fishes 

 taken from grassy bottoms. One of the latter, one foot in length, was 

 gray, violaceous above, each scale olive-green at base. Lower parts 

 tinged with creamy-orange. Head more purplish, mottled with olive. 

 Cheeks greenish. An undulate blue line below eye, below which are 

 purplish reticulations. Long spines of the dorsal fin greenish at base, 

 orange at tip. Soft dorsal similar, a large black blotch at its base. 

 Caudal grayish, with three rows of dull olive spots. Anal similarly 

 colored ; pectoral light orange. Ventrals blackish at tip, reddish at 

 base. 



Deep-water fishes are brick-red or orange red, the degree of redness 

 being very variable, the markings constant. The adult male has further 

 the vertical fins all blackish at base, the black forming a crescent on the 

 caudal ; frontal region from snout to occiput abruptly blackish ; lower 

 jaw light yellow. The male fish has the cleft of the mouth very much 

 wider than the female. These large-mouthed hog-fish are thought by 

 many fishermen to belong to a different species. One specimen had 

 four elongate spines in the dorsal. 



We have little doubt that Professor Poey is right in referring all the 

 nominal species of LachnokvDim to one, and in retaining for this one the 

 name L. suillus of Cuvier, instead of that of falcatus L., used by Va- 

 lenciennes. 



The Labrus falcatus L. is desciibed as follows : 



" Falcatus, 1 0. L. prima dorsali analique radiis quiufpie primis iner- 

 mibus falcata. D. 2V; P. 17 ; V. 5 ; A. -^\- ; C. 20.
