form of its pharyngeal teeth it differs in a marked degree from all the 
other species of Menticirrhus except M.elongatus. Were it not that M. 
elongatus and M. undulatus are both in several respects intermediate 
between WV. littoralis and the typical forms of Menticirrhus, we should re- 
gard the subgenus Umbrula, based on IM. littoralis, as certainly worthy 
of full generic rank. 
Genus XXII.—PARALONCHURUS. 
Paralonchurus Bocourt, Nouv. Arch. Mus., iv, 21,1869 (petersi). 
TyPE: Paralonchurus petersi Bocourt. 
This genus seems to be most nearly related to Loncehurus, being in 
some respects intermediate between that and ordinary Sciznoids. But 
one species has been described.

Paralonchurus petersi Bocourt, Nouy. Archives du Muséum, iv, 1869, 22 (San Salva- 
dor). Jordan, Proc. U. 8S. Nat. Mus., 1886 (Panama). 
Habitat.—Pacifie coast of tropical America, Panama. 
This rare species is now known to us from the original account of Dr. 
Bocourt and from Dr. Jordan’s notes on the original type in the museum 
at Paris. Specimens were later taken by Dr. Gilbert at Panama, but 
all of these have been destroyed by fire. 
A second species of Paralonchurus was obtained by Dr. Gilbert, but 
the typical specimens were destroyed by fire and no description has 
been published. 
The following is Bocourt’s description :

“ CARACTERES.—Corps allongé comprimé; la plus grande hauteur, 
prise 4 la naissance des pectorales, est contenue quatre fois dans la lon- 
gueur (la caudale non comprise), la téte y entrant trois fois et demie. 
Museau déprimé, percé en avant d’un gros pore; deux lobes arrondis 
au-devant de la bouche, au-dessus de chacun desquels se trouve un 
autre pore. Diameétre horizontal de Veil, compris trois fois et demie 
dans la largeur de l’espace interorbitaire, et prés de dix fois dans la
