478 GLYCERA LAPIDUM. 



small cirri. Colour yellowish-white or in some slightly pinkish. Proboscis clavate, with 

 a rich covering of filiform papillae with crenated edges, four blackish-brown teeth hooked 

 at the tip and also thinned off at the other end, and with a bifid spur at one side. The 

 foot has a single spine in front, but about the thirty-fifth the dorsal lobe, instead of being 

 folded backward, projects straight outward, and dorsal bristles are present, though the 

 second spine only appears about the forty-fifth foot. The typical foot presents three 

 pointed lobes and a small dorsal cirrus above it, the third or inferior lobe, which Ehlers 

 says is larger, being the conical ventral cirrus, whilst the hind lip is broad and rounded. 

 The ventral bristles (compound) are in two groups and fan-like in arrangement ; more- 

 over, the extreme dorsal and ventral bristles are stronger than the central in the posterior 

 region of the body. 



In the epitocous form the body is longer, the feet are longer and more prominent, 

 and the spines and bristles longer and more attenuate.
