Specific Characters. — Head somewhat short and broad. The posterior eyes are 

 nearer each other than in H. imbricata, while the anterior are larger and more visible 

 from the dorsum. Median tentacle rather long, with just a trace of a dilatation below 

 the filiform tip, and its surface has sparsely distributed short clavate cilia. Palpi appa- 

 rently smooth, but show minute papillas under a high power. Body somewhat elongated ; 

 segments thirty-eight, either pale or variegated rather prettily with brown. Segmental 

 eminences and papillge distinct. Scales somewhat adherent, thin, but fairly tough ; first 

 pair rounded, rest reniform-ovate, their surface densely covered with minute papillae; 

 colour pale or brownish, sometimes with a broad ring. Feet with a long acute process 

 above the spine. Dorsal bristles long, gently tapered, with very close rows of short 

 spines, and the point rather blunt except in the external forms. Ventral slender, with a 

 long spinous region and a very short, smooth, bifid tip. Dorsal cirri elongated, tapering, 

 and with sparsely distributed short clavate cilia ; ventral slender and rather elongate, 

 also with a few short clavate cilia.

Habitat. — Not uncommon between tide-marks, under stones at Herm, and also in 

 the tubes of Ghdetopterus ; tossed on shore amidst sponges, sea weeds, and corallines at 

 the west sands, St. Andrews (E. and R. M.) 5 in the stomach of the cod and haddock at the 

 same place (E. M.), at Plymouth, Moray Frith, and various parts of the British coast. 

 Ehlers found it ranging in the ' Porcupine ' to 767 fathoms on Holtenia- ground with mud 

 and globigerina-ooze. Extends to the Mediterranean.
