form of its pharyngeal teeth it differs in a marked degree from all the 

 other species of Menticirrhus except M . elongatvs. Were it not that M. 

 elongatus and M. undulatus are both in several respects intermediate 

 between M. Uttoralis and the typical forms of Menticirrhus, we should re- 

 gard the subgenus Umbrula, based on M. Uttoralis, as certainly worthy 

 of full generic rank. 



Genus XXII.— PARALONCHUEUS. 

 Paraloncliurus Bocourt, Nbuv. Arch. Mas., iv, 21, 1869 {petersi). 



Type: Paraloncliurus petersi Bocourt. 



This genus seems to be most nearly related to Lonclmrus, being in 

 some respects intermediate between that and ordinary Scisenoids. But 

 one species has been described.

Par al on churn* petersi Bocourt, Nbuv. Archives dn Museum, iv, 1369, 22 (San Salva- 

 dor). Jordan, Proc. U. S. Nat. Mns., 1886 (Panama). 



Habitat. — Pacific 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 th ese have been destroyed by fire. 



A second species of Paraloncliurus 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 :
