mouth and stronger teeth, and is probably identical with impressus. 
Congromurcena mellissii Gunther seems to belong here rather than under 
the synonymy of mystax , where it is placed by Dr. Steindachner. Conger 
opisthophthalmus and Conger microstomus seem to be the same, and speci- 
mens recently obtained by Dr. Gilbert from the Galapagos Islands seem 
referable to this species. Should the American species prove different, 
it wiil stand as Ophisoma opisthophthalmus 
115. OPHISOMA MACRURUM. 
Ophisoma macrurum Gilbert, mss. (Gulf of California). 
Habitat: Gulf of California. 
Etymology: Maxpoq, long ; obpd, tail. 
One specimen, 9J inches long, was obtained by Dr. Gilbert in the Gulf 
of California. 
116. OPHISOMA MYSTAX. 
Murcena mystax De La Roche, Ann. Mus., 328, fig. 10, 1809 (Barcelona) ( fide Giinther). 
Conger mystax Risso, Eur. M6r., hi, 203, 1826. 
Congermurcena mystax Kaup, Apodes, 110, 1856 (copied). 
Congromurcena mystax Giinther, vm, 43, 1870; Steindachner, Ich. Beitrage, xii, 2, 
1882 (Spalato). 
Echelus nebulosus Rafinesque, Caratteri, 64, 1810 (Sicily). 
Habitat: Mediterranean Sea and eastern Atlantic. 
Etymology: Mbara^ upper lip; the original type having a thick and 
swollen upper lip. 
This species is kuown to us only from descriptions. According to 
Steindachner, Congromurcena mellissii is identical with Conger mystax 
of De La Roche. The differences between mystax and balearicum , how- 
ever, seem to lie in the swollen lips, the greatly projecting upper jaw, 
and the longer tail of the former, and in these respects mellissii wholly 
agrees with balearicum. 
117 OPHISOMA PRORIGERUM. 
Ophisoma prorigerum Gilbert, mss. (Panama; Ecuador). [Two specimens: one 10£ 
inches long from off the coast of Ecuador; the other from the Bay of Pan- 
ama.] (Gilbert.) 
Habitat: Pacific coast of tropical America. 
Etymology: Proru, prow; gero , I bear. 
118. OPHISOMA NITENS.

Panama, 8° 47' N., 79° 29' 30" W., in 14 fathoms).
