FISHERY BULLETIN: VOL. 75, NO. 4 



FIGURE 3. — Holotype of Exechodontes daidaleus n.gen. and 

 n.sp.,USNM 211797. A. Left pelvic rays; the tips originally were 

 straight at about a right angle to main axis. B. Outlines of 

 selected vertebrae traced from a radiograph with the aid of a 

 camera lucida: a, vertebra no. 14; b. no. 20; c, no. 50; d, no. 80. The 

 lines equal 1 mm. 



104 and 27 of SL, not reaching to above anus. 

 Pelvic fins with two rays, appearing as a pair of 

 small nipples below and slightly behind bases of 

 pectoral fins, their length about 6 of SL. The rays, 

 however, are much longer, 31 of SL, originating 

 anterior to the pectoral fins and lying for most of 

 their length horizontally beneath the skin with 

 only their distal ends bent sharply into the visible 

 nubbins (Figure 3). 



Dorsal fin originates behind bases of pectoral 

 fins, above about middle of their length, 235 of SL 

 from tip of snout and 786 from base of caudal fin, 

 with 86 rays. Anal fin originates below base of 

 12th ray of dorsal fin 341 of SL from tip of snout, 

 683 of SL from base of caudal fin, and 215 of SL 

 from nipples of pelvic fins, with 79 rays. Caudal fin 

 38 of SL, with a total of about eight rays. 



Color (in alcohol) very pale yellow-brown, al- 

 most white, with large, scattered brown 

 melanophores, especially over ventral two-thirds 

 of body which is therefore slightly darker than 

 upper one-third. Small to medium-sized (about 1-3 

 mm in diameter), irregularly shaped and placed 

 brown spots on upper half of body, rather widely 

 spaced (separated by at least their own diameter). 

 Cheeks and snout darker than body, with more 

 numerous melanophores; brown pigment present 

 in an arc around front of eyes; tip of snout brown. 

 Lower jaw with darker areas of larger and more 

 numerous melanophores. Darker pigment present 

 along bases of posterior parts of dorsal and anal 

 fins, and base of caudal fin. Pelvic nipples brown; 

 pectoral fins with brown pigment. Peritoneum 

 very dark brown, showing through belly as dark 

 blue-grey; viscera pale. Lining of mouth and 

 pharynx pale. Anus ringed with black. 



Name. — From the Greek daidaleos, dappled or 

 spotted. 



ACKNOWLEDGMENTS 



Upper part of small intestine greatly enlarged, 

 about equal in volume to empty stomach. Two very 

 blunt, short and broad pyloric caeca just posterior 

 to thick and muscular pylorus. Gallbladder large 

 and transparent, lying between liver and enlarged 

 upper intestine. A pair of thin gonad chords ex- 

 tending from midway in length of body cavity al- 

 most to anus indicate holotype is a male. 



Pectoral fins with 15 rays, rounded in outline 

 when rays spread, their length and width of base 



I thank Harvey R. Bullis, then Director of the 

 Pascagoula Laboratory of the Bureau of Commer- 

 cial Fisheries, for the opportunity of joining the 

 Oregon II and for permitting me to retain selected 

 fishes from the cruise, including the new zoarcid. I 

 also thank the crew and scientists of the Oregon II 

 for their friendliness and cooperation, especially 

 Benjamin Rohr who kindly helped me identify and 

 preserve the collections. Daniel M. Cohen of the
