84 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 97 
(Gregory and Conrad, 1936, fig. 4, p. 31). Among known iniomids 
it appears to be most closely related to Veoscopelus Johnson (1863, 
p. 9, pl. 7) and Scopelengys Alcock (1890, p. 302), differing promi- 
nently from both by the continuous vomerine dentition—whence the 
generic name, Solivomer, meaning single vomer. Its relationships 
are discussed in greater detail under the specific description that 
follows.

Diagnosis—A myctophid without photophores, with normal eyes, 
with large scales (41 or 42 in lateral line) which are ctenoid on 
body, cycloid on head; maxillary greatly expanded posteriorly; 
vomerine teeth in a single patch; all of the teeth granular. 
1 Since the beam trawl used by the Albatross did not have a closing device, the precise 
depth of capture is not known.
