432 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 
76. Oligocottus acuticeps sp. nov. 
_Most nearly related to O. globiceps, with which it agrees in the slender curved 
preopercular spine, not forked at tip, and in the absence of prickles on body. It 
differs strikingly in the small head, which tapers rapidly forward to the sharp — 
slender snout, and in the narrow mouth with lateral cleft, as seen in all other species 
of the genus except globiceps. 
Head 33 to 33 in length, slenderer and with sharper snout than in O. maculosus. 
Length of snout equaling diameter of eye, 4 in head. Interorbital space slightly 
concave, its width one-half eye. Maxillary reaching a vertical just in front of pupil, 
3in head. Cardiform teeth on jaws, vomer and palatine bones. 
Preopercular spine slender, sharp, curved upward and inward, neither notched — 
nor forked. Preopercular margin unarmed below it. Nasal spines sharp. Occiput — 
without ridgesor spines. Opercle thickened above, ending behind in a rounded lobe; 
without definite ridge or spine. Branchiostegals 6. No evident pore behind last 
gill. Gill-membranes broadly united, free from the isthmus. 
A cirrus at inner base of nasal spines; 3 pairs evenly spaced on top of head, one 
above orbits, one posteriorly on occiput, and one midway between these two; a — 
cirrus at angle of opercle; one above each pore of anterior portion of lateral line. 
Sides of body otherwise smooth, without further cirri and without axillary or other 
prickles. 
Dorsal fins usually slightly joined at base. Pectorals reaching to or slightly 
beyond front of anal fin. Ventrals short, equaling length of snout and eye, extend- 
ing little more than half way to front of anal. Anus anterior in position, thus — 
differing from O. maculosus and O. analis, its distance from base of ventrals but 
halfits distance from front of anal fin. Pores of lateral line 33, each of the anterior 
15 usually accompanied by a cirrus. Fin rays in seven specimens are as follows:

Color varying with the surroundings, often nearly uniform bright green. When 
dark markings are present, we usually find six short, wedge-shaped dorsal bars, 
widening rapidly below and joining one another by their extreme tips. Below these 
a dusky, wavy lengthwise streak and another wider one below lateral line. The 
latter is marked posteriorly by round white spots, the size of pupil. Occiput dusky. 
A black bar from eye to snout; one trom eye to behind maxillary; one from eye to 
base of preopercular spine. The interval between these subocular bars may be 
silvery white. Thespinous dorsal often shows two dark bars, asin O. globiceps. Ven- 
trals plain. Fins otherwise finely mottled or indistinctly barred. Some or all of 
these dark markings may be absent. 
Four specimens, the largest 47 mm. long, from tide pools at Unalaska, are the types 
of the species. Three others were taken in Departure Bay, Vancouver Island. 
77. Paricelinus thoburni sp. nov. (Plate 30.) 
A single specimen, 165 mm. long, was dredged at station 3350, off the coast of 
Oregon, at a depth of 75 fathoms. 
Our specimen agrees in most of its characters with P. hopliticus Eigenmann, but 
differs from the description of the latter (The West American Scientist, October, 
1889, p. 131) in the following important respects: P. thoburni does not possess a 
pair of long barbels at the chin, but has others, not mentioned, above eye and along 
margin of preopercle. The suborbital stay does not possess two strong upwardly 
directed spines behind eye, but is thickly beset with a number of crowded smaller 
ve
