lateral line; nostrils with short tuhes; dorsals united at base, the spines 

 with short filaments, middle spines 3 in head, middle rays of soft dorsal 

 2 in head: caudal and ventrals If in head, ventrals usually reaching vent 

 or anal, but sometimes falling short of each ; pectoral 1 in head, reach- 

 ing to or beyond anal. Color dusky, below colorless, a pale bar across 

 occiput (often absent), another between dorsals, 2 across body under soft 

 dorsal and another behind soft dorsal; sometimes the pale color predomi- 

 nates and the dusky portion is left as 4 bars; sometimes plain dusky with- 

 out cross bars; spinous dorsal dusky with 3 or 4 colorless spaces on the 

 web; other fins barred with series of dusky blotches, ventrals sometimes 

 colorless ; 5 to 8 oval white spots behind pectoral, sometimes obscure ; males 

 with inner ray or rays of ventral tuberculate or serrate. This species 

 differs from Forocottus sellaris in the presence of cirri on top of head ; it 

 has more numerous fin rays and more cirri on head than Porocottus quad- 

 rifilis. This species is the most common fish in the rock pools at Karluk, 

 where many specimens were taken. These are in the U. S. National 

 Museum, in the collection of the U. S. Fish Commission, and in that of 

 Leland Stanford Junior University. (Named for Mr. William B. Bradford, 

 secretary of the Alaska Packers' Association, from whom the collector 

 received many favors.)

745(a). SIGMISTES, Rutter, new genus. 

 Xigmistes, RUTTER, MS., new genus (cauliat). 



This genus differs from Oxycottus, to which it is most closely related, in 

 the deep compressed body, strongly arched lateral line, long dorsal fin, 

 and large mouth. Body deep and compressed ; skin smooth; lateral line 

 complete, strongly arched anteriorly; gill membranes united, free from 

 isthmus ; no slit behind last gill ; preopercular spine simple, short, strongly 

 curved upward, anal papilla large; vent immediately behind ventral fins, 

 about f of distance from gill membrane to anal ; ventral rays 1, 3. (tiiyfta, 

 the letter S, from the form of the lateral line.) 



2382(a). SIGMISTES CAULIAS, Rutter, new species. 



Head 3f ; depth 3. D. IX, 20 (IX, 21 in 1 specimen) ; A. 15 (14 in each 

 of 2 specimens); P. 13. Back elevated, body compressed; eyes lateral, 

 4 in head ; snout 3 ; cleft of mouth lateral ; maxillary 2 in head, reaching 

 to below pupil (only 'a little past front of eye in 1 specimen). Teeth 

 coarse, cardiform, the inner row of upper jaw enlarged, almost canine- 

 like; a similar pair in inner series of mandible, near symphysis; a small 

 patch on vomer, and 1 on front of palatines ; preopercular spine small, 

 sharp, appressed, strongly curved upward, the preopercular margin with- 

 out spines or tubercules below it; nostrils in short tubes, 1 pair directly 

 behind nasal spines, 1 pair lateral, directly in front of eyes ; nasal spines 

 strong, sharp ; a pair of tufted cirri above eyes, a pair simple or branched 

 at occiput, and a pair of simple ones halfway between these ; a filament 

 on nasal spine, a series of 3 or 4 short ones on margin of preopercle and ]
