4 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 122 



interorbital space 19 and 15; snout tip to anus 245 and 263; snout tip 

 to dorsal origin 105 and 103; length of pectoral fin 22 and 21; distance 

 from lower edge of gill opening to upper edge of base of pectoral fin 

 14 and 15; length of nasal tube 7 and 7; length of caudal fin 17 and 21. 



Remarks, — This new species has two unique characters for the 

 family Zoarcidae. The first is the anatomical nature of the penulti- 

 mate vertebra, described above and diagrammed in figure 2. One 

 might cast doubt on the uniqueness of the penultimate vertebrae were 

 they unlike in both specimens. Since they are basically identical, 

 both show rudiments of three vertebrae, each supporting a neural 

 spine and three, or possibly four, hemal spines. The second character 

 is the large number of vertebrae 144 to 150, more than I have noted 

 for any other genus in the family Zoarcidae. 



For comparison purposes with the new species, radiographs of type 

 specunens of zoarcids in the United States National Museum (USNM) 

 collection have been prepared by Mrs. Dorothy Ann Hubbs (except 

 for those specimens too brittle or too soft to remove from the jars). 



An examination of these radiographs definitely did not show any 

 modification of the penultimate vertebra like that observed for 

 Nalbantichthys. 



The scientific name of each species as published in the original 

 description is listed alphabetically (along vnth my counts of the 

 abdominal and caudal vertebrae) as follows:
