76. Oligocottus acuticeps sp. nov. 



Most nearly relati'd to O. glohiceps, 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 niontli with lateral cleft, as seen in all other species 

 of tbe genus except glohieepn. 



Head 3A to 3| in length, slenderer and with sharper snout than in 0. 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, 

 3 in 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 ridges or spines. Opercle th ickened 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 0. maculosus and 0. analis, its distance from base of ventrals but 

 half its 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 from eye to behind maxillary; one from eye to 

 base of preopercular spine. The interval between these subocular bars may be 

 silvery white. The spinous dorsal often shows two dark bars, as in 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, 16.5 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 7*. hopliticus Eigenmann, but 

 differs from the description of the latter (The West American Scientist, October, 

 1889, p. 131) in the following important res])ects: P. thohurni 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
