cells and granules taking in the stain. On eacli side of this 

 area is a tentacle, the base of which is enlarged and the tip 

 filiform and tapering. 



The entire body has a more or less circular outline, and 

 the four pairs of feet radiate outward chai'acteristically, the 

 anterior pair being wide apart and directed almost straight 

 outward, or witii a slight obliquity forward, whilst the last 

 pair is somewhat smaller und more nearly in atrau»vei-se line. 

 Each foot consists of a setigeious process tapered toward the 

 tip, so that it resembles a long cone with a tuft of translucent., 

 slightly curved, simple bristles issuing from it in a fan-like 

 manner. Each bristle has a translucent straight shaft, the 

 curved region at the tip being finely spinous on its convex 

 edge. Amongst these is a shorter, stouter form also curved 

 at the tip, but smooth. Shorter and more slender bristles 

 apparently represent the dorsal series, and, in all, these form 

 a group at the tentacle, their tips, which are finely serrated, 

 curving inward at the side of the head. A similar tuft 

 occurs on the dorsum of each foot, though in the smallest 

 (youngest) they are not visible on the two posterior feet. 

 The curvature of these bristles may be partly due to preser- 

 vation. The alimentary canal seems to go straight backward 

 to the vent, the last portion, occupying a little less than a 

 third of the lengtb of the body, being more deeply stained. 

 A median fissure separates two minute and somewhat ovoid 

 lobes between the bases of the posterior feet. 



So f;ir as can be observed, this would seem to be the pelagic 

 young of Euphrosyney probably of E. fuUosa, the common 

 species of the more southern waters. The general outline, 

 the cephalic lobes, so largely developed in the young, the 

 ovoid anal processes, and the nature of the feet and bristles 

 all point to this conclusion. Such young examples seem to 

 be rare, and I am indebted to Mr. Chadwick's courtesy for 

 the slide containing the examples. 



Hub. A single example of Clirysopetalum debile of the 

 family Palmyridge was dredged ou a bottom of sand and 

 shells in Clew Bay {Southern). 



The occurrence of a representative of a genus character- 

 istic of the warmer seas on the west coast of Ireland 

 indicates the richness of tliis remarkable region, and the 

 possibility of further interesting discoveries yet in store for 

 the marine zoologist. In the description of Palmyra aurifera, 

 Savigny, in the 'Challenger' Annelids, Chrysopetalum debile 

 is alluded to "^ in connection with the presence of scales.
