ii, 18G0, fig. 10). The figure is but a sketcli, and is inaccurate in many 

 respects. 



3d. The larger individuals are always sold as "halibut," attain the 

 dimensions of the true halibut, and are evidently identical with Ayres's 

 species. 



4th. The small sinistral individuals have all the characters of Para- 

 liclitliyfi maculosKs Gir., excei)t the position of the eyes and color, and 

 some difference in the color of the spots. 



These reasons, although they point strongly towards identity, do not 

 prove it ; but I have lately i)rocured an individual (No. 5) which has the 

 characteristics of Ayres's species, yet is dextral, thus agreeing exactly 

 with that of Girard ; so that I can now add to my reasons — 



5th. A sjiecimen of dimensions intermediate between that of Girard 

 (7' long) and the large individuals before mentioned has the characters 

 of U. californica, but is dextral, as stated by Girard in his description of 

 P. maculosm. In this specimen, the interorbital area is proportionally 

 much wider than in the smaller examples, exceeding the longitudinal 

 diameter of the eye ; and the row of spots along the dorsal and abdomi- 

 nal outlines, so evident in the small individuals, is almost obsolete, 

 traces of one or two of the posterior ones being all that is left of them. 

 The principal caudal rays are many times dichotomized, the base of the 

 fin is fleshy, and its scaly covering is very conspicuous ; some of the 

 rays of the right pectoral are twice bifurcate ; about eight of the poste- 

 rior rays of the dorsal and anal are bifurcate ; each ray of the dorsal and 

 anal (except the most anterior and posterior) is seen to have, upon its 

 anterior face, a roAV of i^rincipal scales, and numerous accessory scales, 

 all resembling those of the body, but smaller ; each scale of the body is 

 seen to be followed by several supernumerary scales arranged around 

 its posterior margin ; and the pectoral of the colored side has only ten 

 rays; that of the blind side eleven. As this is the only dextral exam- 

 j)le out of about ten individuals that have come under my observation, 

 I am inclined to believe that dextral specimens are comparatively rare, 

 at least on this part of the coast. As the generic name Faralichthys 

 has precedence over that of Uropseita, it must be retained for the spe- 

 cies, which must henceforth be known as FaraUchthj maculosus.
