NO- 3598 ZOARCID FISH — SCHULTZ 3 



spines are represented with only the first bearing a dorsal fin ray. 

 The degenerate hemal spines are definitely three mth the last divided 

 distally into two elements, each bearing an anal ray, possibly the 

 posterior hemal branch representing a fourth vertebra. The penulti- 

 mate vertebra was counted as one vertebra. I do not consider the 

 penultimate vertebra of Nalbantichthys as abnormal smce both 

 specimens are alike m that character. 



The somewhat rudimentary fleshy pectoral fin as seen in one of the 

 radiographs has six rays; no lateral line was observed; peritoneum 

 blackish; mouth terminal, lower jaw slightly shorter than upper jaw; 

 teeth on jaws conical, uniserial on sides and a patch of canines at tip 

 of both jaws; margin of eye not free; eye covered with a dermal 

 membrane; by dipping the head of the holotype in a solution of

 Schultz.) 



alizarin the pores on the head became visible as shown in figure 2. 



The follo^ving counts were made, first for the holotype, then for the 

 paratype, respectively: Dorsal rays (including those in middle of 

 caudal) 156 and 150; anal rays to midcaudal 130 and 124; vertebrae 

 25+125 = 150 and 25+119=144; branchiostegals 7 and ?; pectoral 

 rays 6 and ?. 



Measurements (made on the holotype and paratype and expressed 

 in thousandths of the total length, first for the holotype, then the 

 paratype): Total lengths 138.3 and 110.3 mm; length of head from 

 snout tip to upper edge of gill opening 100 and 105; depth of head at 

 gill opening 77 and 75; diameter of eye 14 and 16; distance from tip 

 of snout to rear of maxillary 44 and 54 ; longest diameter of gill opening 

 16 and 16; tip of snout to front edge of eye 25 and 27; width of fleshy
