preopercle with a long, slender, curved spine at its upper edge; two 

 smaller spines below this pointing downward and forward; a sharp 

 spine on lower edge of opercle; nasal spines not evident, palatines 

 naked; vomer with a small patch of weak teeth. Lateral line com- 

 plete. Minute prickles covering a small area beneath pectoral; 

 other parts of body naked and smooth. Dorsals entirely separate, 

 the membrane of spinous dorsal just reaching base of first ray; 

 middle spines highest, 3 in head; longest rays about 2.3. Anal rays 

 about 2.8; both dorsal and anal falling far short of caudal when 

 depressed. Ventral rays I, 4, not reaching vent. Pectorals reaching 

 a vertical through base of first anal ray. 



Color light below, clouded with dusky above; four more or less 

 definite saddle-like spots on back; two below spinous dorsal and two 

 below soft dorsal; a narrow, dark band on base of caudal; rays and 

 spines of fins with rows of dark spots.

MYOXOCEPHALUS YESOENSIS, new species. 



One specimen of a Myoxoceplialus obtained at Hakodate does not 

 appear to belong to a known species. It is characterized by a short, 

 robust body without plates or scales except along the lateral line, 

 short snout and small eyes, verrucose skin on upper parts of head 

 where the ridges are very low, short postorbital and occipital tentacles, 

 and two short preopercular spines. An almost colorless chin and 

 throat and the short spines distinguishes it from M. stelleri, and the 

 small eyes alone will prevent it from being confused with M. nivosus. 

 It appears to most closely resemble M. brandti. It has, however, a 

 smaller eye, the longitudinal diameter being considerably shorter 

 than the snout and equal to the width of interorbital space. The 

 upper preopercular spine is shorter and there are no small plates 

 below the lateral line. 



Head 2.4 in length to base of caudal; depth 3.5; depth of caudal 

 peduncle 5 in head; eye 5.6; snout 3.5; interorbital space 5.6; maxil- 

 lary 2.2; D. IX, 13; A. 10; P. 17; pores in lateral line 34. 



Skin on upper parts warty; very short postocular and occipital 

 filaments; postocular region with short, digitate ridges, some of 

 which approach the median line while others extend backward and 

 unite with an uneven, low ridge which extends from posterior border 

 of eye, along occiput to nape where it breaks up into minute forks; a 

 second ridge parallel with and a little below the occipital ridge passes 

 backward and after one or two interruptions becomes continuous 

 with the humeral spine; interorbital stay with a bony surface; upper
