fi7l 



margin straight; frill-mi'iiil'i'MMcs rather wiilcly joined acmss throat an. I forniiiitr a wide free liorder 

 postericirly. 



Profile but little elevated at front of iirst dorsal, the base of whieli is not oblique; seeond dorsal 

 spine broken, the basal i)ortioii bearing S strong distantly placed hooks; longest dorsal ray 0.7 length of 

 head; seeond dorsal very low throughout; base of first dorsal 0.8 the interspace between dorsals; anal 

 low, originating under middle of first dorsal; iiectoral extending to opposite twelfth anal ray, its length 

 0.7 that of head; tips of veiitrals injured, so their length can not be given; anal opening anterior in 

 po.sition, it,s distance from inner base of ventrals being 0.7 its distance from front of anal tin. 



Sciiles on back and sides of body have all been lost; on jiredorsal region each scale hasaliout 10 

 slender distinct spines arranged in 1 median and 2 parallel lateral series; the spines of the median series 

 little longer than the others, none of them located on ridges; side and upper part of head, including 

 snout, entirely invested with spinous scales; lower siile of snout and anterior half of sjjace between 

 mouth and infraorl)ital ridge, naked; jiosterior half of supraoral area scaled continuously with the 

 cheek; mandible with a few scales, the others apparently having been lost. 



(.'olor grayish, darkened by the broad dusky margins of the scales; sides and lower surface of 

 head and abdomen jet-black; mouth blackish; lining of opercles black, the gill-cavity otherwi.-:e light; 

 liningofal)doniinal cavity blackish; barbel whitish; ventral tins black, other tins dusky transluc-ent. 



But one sjiecimen was procm-ed.

species. 



Type, 125 mm. long, from station .3925, off the south coast of Oahu Island, de]itli 2!t!t t 

 fathoms; type, No. 51608, U. S. Nat. Mus. 



Strongly resembling .1/. eclene.t Gilbert A Cramer, also from Hawaiian waters, lint differing in the 

 much smaller eye, the nunilier of dorsal and ventral rays, the smooth rostral tuljercies, the armature of 

 scales, and the color.

Fl«. 2r,2.—Mamiuruslidji talus (Jilliert, lU'w species. Tyjii'. 



Body rather short and deep, tUv dej-th at ..rigin of dor.-al c..r]taiiicd 1.2 times in length of head. 

 First dorsal ii, 12; V. S; P. 24; eleven scales in an oblique series from lateral line to base of dor.-^al 

 spine. 



Head short, cuboid, with vertical cheeks and vertical anterior jirofile to snout; axial length ..f the 

 very short snout 0.7 its widtli. which e(|nals the greatest diameter of orbit; snout ending hi a small 

 perfectly smooth tubercle, from which extends backward a median ridge, which is angulated at a 

 point mi.lway between nostrils; a sharp ridge bounds the nasal fos,sa above and joins the supraorbital 

 run; no distinct lateral jiair of rostral tubercles, and no spines on any of the exposed points or ridges; 

 mouth small, slightly oblique, scarcely overpassed by the rostral tubercle or the suborbital ridge; max- 

 illary reaching a vertical line which crosses eye half way between its anterior edge and the front of 

 liupil, its length 3.:nn head; upi)er jaw with a moderate villiform band of teeth, those of the outer 

 .series definitely enlarged, forming small canines; mandibular tc-eth in a narrow villiform l)and- barbel 

 small, 0.25 diameter of orbit; .listance from front of premaxillaries to rostral tulx^rcle 0.7 diameter of
