12. GYMNOTHORAX VICINUS. 
Murcenophis vicina Castelnau, Anim. Amdr. Sud, Poiss., 81, pi. 42, fig. 4, 1855 (Bahia). 
Murcena vicina Gunther, vm, 121, 1870 (Bahia). 
Thyrsoidea maculipinnis Kaup, Apodes, 83, 1856 (Gold Coast); Dmndril, Arch. Mus., 
x, 260, pi. 28, fig. 1 ( fide Gunther); Bleeker, Verh. Holl. Maatscli. Haarl., 
129, tab. 27,1862 ( fide GUnther) ; Troschel, Wiegm. Arch., 237, 1866 {fide 
Giintlier). 
Murcena maculipinnis Gunther, vm, 124, 1870 (Cape Verde Isl. ; Fernando Po; Mexico). 
Gymnothorax maculipinnis Jordan, Proc. U. S. Nat. Mus., 1890 (Bahia). 
Thyrsoidea cormura Kaup, Aale Hamb. Mus., 23, 1859 ( fide Gunther). 
Toeniophis cormura Kaup, 1. c., tab. 3, fig. 2 ( fide Giinther). 
Thyrsoidea marginata Kaup, 1. c., 24 {fide Gunther). 
Tceniophis marginata Kaup, 1. c., tab. 4, fig. 1 {fide Gunther). 
Gymnothorax versipunctatus Poey, Enumeratio, 156, 1875 (Cuba). 
Habitat: Atlantic Ocean, West Indies to Cape Verde Islands and 
Africa. 
Etymology: Latin, vicinus, near (to Gymnothorax moringa), 
A specimen, collected by the Albatross at Bahia, seems to be identical 
with Murcena vicina of Castelnau, which was obtained in the same 
locality. This seems to be the same as the maculipinnis of Kaup, and 
we have therefore adopted the name vicinus instead of the latter name. 
Another specimen before us (6737, U. S. K. M., without locality) evi- 
dently belongs to the same species. We refer the names cormura and 
marginata to this species on the authority of Dr. Giinther. 
13. GYMNOTHORAX VIRESCENS. 
Gymnothorax virescens Poey, Enumeratio, 156, 1875 (Cuba). 
Habitat: West Indian fauna. 
Etymology: Virescens, greenish. 
This species is known only from Poey’s account. 
14. GYMNOTHORAX POLYGONIUS. 
Gymnothorax polygonius Poey, Ann. N. Y. Lyc. Nat. Hist., 68, 1872 (Cuba); Poey, 
* hjuumeratio, 158, 1875. • 
Sidera vicina Jordan, Proc. U. S. Nat. Mus., 34, 1886 (Havana). (Not Murcenophis 
■ vicinus Castelnau.) 
Habitat : West Indian fauna. 
Etymology : Latin, marked with polygons. 
Of this species we have two examples. One of these was obtained 
by Dr. Jordan at Havana. Tt was at first identified as Gymnothorax 
vicinus , but Castelnau’s species seems to be different from this. There 
is no doubt that this is the original of Poey’s G. polygonius , although 
the polygonal markings are very obscure. The other specimen (9825 IT. 
S. 1ST. M., 28 inches long) was sent from Cuba by Poey. It agrees per- 
fectly with our specimen, a*»d it may be Poey’s original type.
