 The maxillary b;irtx-ls extend to liistal fourth of pectoral si>ine; outer mental liarijels to its middle, 

 inner mental barlK-ls to itslxise. The fontanel j(^roove fails to reaoii the haseof the occipital i)rocess by J 

 the diameter of the eye. The palatine jxitches of j^ranular teeth are wider than tijjured by Kijjenmann, 

 the two se|>;irated by a distance equal to or slij,ditly in excess of the diameter of the eye. The [xitclies 

 vary in size antl sha|)e in the two specimens, and on o|)posite sides of the same individual. In one 

 s|)ecimen are two iletached teeth laterally on the head of the vomer, on one side only; none in the 

 other s|x?cimen.

Family SYMBRANCHID^. 



53. Symbranchus marmoratus Blwh. 



Abundant in a fresh-water pond at MiraHores, where it i.s trapped for food. 

 As none could be taken with the seine, it seems probable that the species burrows in 

 the nuid. The few specimens secured were all brownish, variously marbled witli 

 yellowish. 



Family LEPTOCEPHALID^. 



54. Congrellus gilberti JJoiiula-ss-Oglibij. 



Conf^rcllns gilberti Douoi.ass-Oc;ilbv, 1898, p. 288. 

 Ophisoma (?) baharicum Gilbert, 1891a, p. 349. 



Dredged by the "Albatross," Station 2797, Panama Bay, 33 fathoms; recorded 

 by Gilbert as Opliimmn (?) halearicum. The species is based exclusively on Gilbert's 

 description above cited. The type si)cciinens are deposited in the United States 

 National Museum. 



55. Congrellus nitens {Jonlnu <(• Hollman). 



One specimen dredged by the "Alliatross" in Panama Bay, Station 2799, 

 29^ fathoms (Gilbert, 1890 6, p. 4-50). 



56. Congrellus proriger (Gilhcrl). 



A co-type of this species was dredged by the "Albatross" in Panama Bay, 

 Station 2799, 29^ fathoms (Gilbert, 1891a, p. 35).
