Having seen the first part of the first volume of the Proceed. Calif. 

 Acad. Nat. Hist., I am enabled to add the formula of the fins in this 

 species : Dr. Ayres, however, says that the vertical fins are so united 

 that it is not easy to enumerate the rays : — 



D. 47. A. 40. C. 11. 



Girard has given an incorrect, or at least unintelligible description 

 of the pectoral fins ; according to Dr. AjTes's account, they have the 

 8£tme form as in L. vulgaris. The gill-opening is small, equal in 

 width to the diameter of the eye ; teeth tricuspid.

It is evident from the short description given by Dr. Ayres that 

 this species is very distinct from L. pulchellus ; but the characters 

 by which it differs from L. callyodon, Pall., have not been pointed 

 out by its discoverer : — 



" The length of the head is one-fourth of the total (the caudal 

 excluded) ; snout rounded anteriorly, not truncated ; longitudinal 

 diameter of the eye nearly one-sixth of the length of the head. The 

 dorsal and anal fins both arise at about the same points as in L. pul- 

 chellus ; they are not continuous ivith the caudal, but terminate at its 

 base, leaving that fin separate and distinct, with a rounded extremity. 

 The dorsal is emarginate a short distance from its origin, giving in 

 a degree the appearance of an anterior dorsal. Plain greenish -oUve, 

 lighter beneath. 



" In the branchial aperture, form of the operculum, teeth, nostrils, 

 pectoral and ventral fins, in the loose attachment of the skin, this 

 species agrees well with L. pulchellus." {Ayres.^

The skin on the crown of the head, on the cheek and on the chin 

 is provided with reticulated folds ; a series of pores runs along the 

 side, and a vertical fold of the skin desc>ends from each pore. The 

 length of the head is two-sevenths of the total ; the width of the 

 bony bridge between the orbits is contained five times and a half in 

 the length of the head, and equals the extent of the snout, which is 

 longer than the eye. GUI-covers with Four spines directed back- 

 wards, two belonging to the operculum and two to the suboperculum. 

 Vomer and palatine bones with a series of conical teeth. Snout
