142 Prof. M‘Intosh’s Notes from the 
and marked by longitudinal veins internally. A marked 
shoulder occurs anteriorly, over which (ventrally) the cutting- 
plate extends backwards. On the inner (dorsal) surface the 
shoulder is boldly marked, the cutting-plate rising from 
each as a broadly lanceolate process with crenations on the 
anterior edge. The cutting-plates in certain examples seem 
to be easily detached, as if they were shed at intervals and 
renewed. 
Dental apparatus of Eunice phylocorallia, F, Buchanan, Enlarged. 
In Roule’s description of the dental apparatus of Z. am- 
phiheliea, Marion, the great dental plates agree in the number 
of the teeth (five). Unfortunately the nomenclature of the 
other parts is not conducive to perspicuity, for he adds that 
there are three denticles on each side, the anterior small and 
the posterior small, and that the anterior is devoid of teeth ; 
the middle carries five and the posterior eight. As no 
mention is made of the azygos plate, considerable dubiety 
remains. 
The anterior feet are characterized by the length of the 
dorsal cirri and the comparative length of the ventral in 
the first seven or eight. Thereafter the ventral become 
short processes of the great glandular mass at their base.
