5G2 Prof. Mcintosh's Notes from the 



bristles dorsally and, ventrally, jointed hooks which have a 

 short terminal piece — with a crown of small hooks and two 

 wings, the adjacent end of the shaft likewise having two wings. 

 There are four pale spines. These jointed hooks continue 

 to the 15th foot and then disappear, their places being taken 

 by simple winged hooks. 



" Of the Eunicea P nonognatha of Ehlers several British 

 species occur. The first is provisionally termed Drilonereis 

 Blisubethce, uhich was procured at St. Andrews in the 

 stomach of a haddock by the lady after whom it is named. 

 It is recognized by the finer and more persistent iridescence, 

 and the bluntly conical head with four eyes in a transverse 

 line at the posterior border, besides the structural features. 

 The black abruptly hooked maxillse are powerful, with a 

 broad base — denticulated on the inner edge — articulating 

 posteriorly with very long black appendages. Great dental 

 plates elongate, black, and nearly rhomboidal, with about 

 six to eight recurved teeth along the inner edge, the first 

 being considerably larger than the others. Antero-lateral 

 plates three, small, each with a single, long, sharp fang, the 

 first or proximal showing in addition a second short tooth 

 at the base of the chief fang. The mandibles form dark 

 brown wedge-shaped plates. The broad anterior edge is 

 slightly roughened, but it is not calcified. A typical foot 

 has a small dorsal lobe sloping outward and upward, a short 

 setigerous lobe, with four or five ordinary spines, a large 

 stout spine with a slightly tapered tip below the others, and 

 a broadly lanceolate inferior lobe directed upward. Bristles 

 simple, winged, tapering, with oblique striae on the wings. 



"\Vhile in the general outline of the body, the shape of the 

 head, and the arrangement of the eyes this form approaches 

 Arabella iriculo); Mont., it diverges in the structure of 

 the foot and also of the dental apparatus, especially in th6 

 comparatively great size of the maxillee and the dimi- 

 nution of the three antero-lateral plates. The large size 

 of the maxillije, again, distinguishes it from Notocirrus 

 (char, amend.), to which it is allied in the presence of the 

 great inferior spines. It seems to approach most nearly to 

 Drilonereis, Claparede ^, though the eyes are borne by the 

 peristomial segment in the species described by that author 

 and De St. Joseph fj and, if the figures are to be trusted, 

 the antero-lateral teeth of the dental apparatus are con- 

 siderably larger.
