LYSIDICE PUNCTATA. 457 



large and deeply concave from side to side, so that about half the length of the upper 

 jaw-apparatus lies in the hollow curved anterior region. A longitudinal black bar on 

 the upper surface. Foot with a dorsal cirrus slightly constricted at the base, and, 

 in spirit, not extending beyond the tips of the bristles. Setigerous region a flattened 

 cone with two strong yellowish spines (tenth foot). The dorsal bristles are curved at 

 the end of the shaft, and the winged tip tapers to a fine point. Below the spines are 

 jointed bristles, dilated at the end of the shaft and serrated on the convex edge. Terminal 

 piece short, with a bifid hook and two wings. In the posterior feet a strong hook passes 

 obliquely downward and pierces the skin below the compound bristles.

Habitat. — Abundant in fissures of gneiss in Guernsey in muddy sand. If the rock is 

 easily split, from the presence of an old crack, the greater is the probability of obtaining 

 large specimens. A fragment also occurred in the Grouliot Caves, Sark. At Herm small 

 specimens are frequently obtained along with Polydora, Dodecaceria, and other Annelids, 

 by breaking off the coating of Lithothamnion on stones between tide-marks. Whether it 

 merely occupies the holes made by other forms or whether it enlarges these is an open
