334 HARMOTHOE ANTILOPIS. 



dorsal bristles, and in the pale semi-translucent scales, but the ventral bristles approached 

 each other closely. A re -examination of all the characters and of Malmgren's description 

 now inclines me to unite them, especially as in the generic characters he states that the 

 dorsal bristles are shorter and thicker than the ventral, while in the specific he says they 

 are much shorter and a little more slender than the inferior bristles. Moreover, if his 

 figure of the dorsal bristle be supposed to be that next the ventral series (always the 

 most slender and elongate), the distinctions more or less disappear. The only doubtful 

 point is the possible existence of a species agreeing in all respects with that from 

 Lochmaddy, but having more elongated dorsal bristles. Levinsen seems to be of the 

 same opinion. 



Few individuals of this form would seem to exist. Only a single example was 

 obtained at Lochmaddy, and one in the stomach of a cod at St, Andrews. Baron de St. 

 Joseph found one in the tube of Lanice conchilega at Dinard. With the two foregoing it 

 forms a special series — closely approaching each other and such forms as the Polynoe 

 crassijpalpa of Marenzeller. 



5. Harmothoe antilopis, Mcintosh, 1876. 



Specific Characters. — Length about three-quarters of an inch or a little more. Head 

 broad behind, peaks truncated in front, two widely separated eyes posteriorly, and a 

 larger pair laterally and below the short peaks, not visible from the dorsum. Median 

 tentacle and tentacular and dorsal cirri moderately long, slightly enlarged below the 

 filiform tip, and covered with numerous cilia with slightly bulbous tips. Lateral 

 tentacles inferior. Palpi of average length — with clavate papillas. Body, moderately 

 elongated, of considerable breadth, bristled segments 33 — 35. Scales fifteen pairs, 

 mostly reniform, entirely covering the dorsum, with long cilia externally and 

 posteriorly and shorter on surface, which also has large horny papillae ending in 

 spines with hispid tips. Dorsal bristles elongated, with smooth tips and very 

 distinct spinous rows (resembling the horns of an antelope), ventral with bifid tips, 

 scarcely hooked, and in some the distal part of the spinous region is narrower than the 

 smooth tip. Ventral cirri rather slender and tapering, with short clavate cilia. The 

 segmental papillae are but slightly marked.
