These, with about 12 rounded knobs on the crown and several low bosses, besides 2 short spines on each cheek give the head a peculiarly bony appearance. The first two or three spines of the first dorsal fin are longest; the fourth and fifth spines are shorter than those further back, giving the fin an outline quite unlike that of any other sculpin; from the third spine backward the fin mem- brane is deeply emarginate between every two spines but expanded at the tips of the latter into irregular flaps; and the margin of the anal fin is similarly but less deeply scalloped between the rays. Furthermore the first dorsal fin originates further forward than in any other Gulf of Maine sculpinâthat is, well in front of the gill openingâand is much longer (16 spines) than the second (12 rays), whereas in our other sculpins the second dorsal is longer than the first. The pectorals are fanlike and the caudal brush shaped as in other Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States Fish Commission.
