NERINE FOLIOSA. 143 



nating posteriorly in a rounded enlargement followed by a short tentacle. Eyes generally 

 present. Body 6 — 8 inches in length, and nearly f inch broad, somewhat flattened 

 dorsally and slightly convex ventrally, little tapered in front, but gradually diminishing 

 posteriorly to a stellate anus. Segments about two hundred. Colour pale orange or dull 

 yellow anteriorly, posteriorly dull yellow with, in some, a tinge of green. Dorsum marked 

 anteriorly by fine transverse lines. Under-surface dull yellow with a median streak. 

 Branchias bright red, but anteriorly the fusion of the superior lamella obscures them. 



Feet with branchise from the second backward, and amalgamated with the large 

 superior lamellas from the second to beyond the fiftieth. Interlamellar notch distinct. 

 Ventral lamella, at first prominent and rounded, becomes narrower and elongated from 

 above downward on the appearance of the winged hooks at the fifty-eighth segment. 

 The winged hooks appear in the superior division after the seventieth bristled foot 

 (sixty-fifth, Mesnil). Bristles of the upper division in front form two groups, a long 

 upper series, and a shorter inferior — all curved, dappled, and finely tapered.
