pore 1 or 2; first, second, third, and fifth supraorbital pores present; 
pectoral rays 14 to 15; vertebrae 145 to 147 (x-ray). 
CoLor IN ALCOHOL: Body and head light brown, lighter ventrally, 
tip of snout and tip of lower jaw dusky; pectoral fins dusky, lighter 
toward base of fin; a large dusky brown spot covering first 8 rays of 
dorsal fin and membrane, outer half of dorsal and anal fin dusky 
brown, basal half and distal edges whitish; lateral line and septum of 
myomere whitish. 
GEOGRAPHICAL RANGE: Madeira. 
Remarks: Giinther (1870, p. 40), described Conger macrops from 
specimens from Bahama and Madeira. The Bahama specimen, B.M. 
1855.9.19.1270, was examined by Dr. Ernest Lachner, and found to 
be Echelus caudilimbatus Poey. Therefore, I restrict the species 
macrops to the other specimen described by Giinther from Madeira. 
Dr. Denys Tucker (British Museum) made a special effort to examine 
the Madeira specimen for me in the Liverpool Museum but was 
unable to find it. 
This species has the greatest degree of differentiation from all 
other species in the genus because of the greater number of lateral 
line pores, the upper edge of gill opening is constantly higher and the 
black spot on the anterior side of dorsal fin is present.
