{Southern). Tlic cephalic region tapers to a slender jioint, 

 wliieh (Iocs not sliow a clavate ti}). The extrndcd proboscis 

 is furnished Avith thirteen slender papillie [Southern). 

 Nuelial organ conspicuous on each side in the front of the ■ 

 first bristle-bundle. The body is fully 12 mm. lonj;, tapered 

 at both ends, but nearly of uniform diameter throughout the 

 rest of its extent. It is rounded dorsally, deeply grooved 

 ventrally from the snout to the anal funnel. Setigcrous 

 segments thirty-three, each with three rings, aiul each ring 

 biannulate [Southern). Tlie dorsal cirri are filiform and 

 fairly long. An eye-speck is situated behind each foot, from 

 the fourth to the nineteenth, and each consists of small 

 spheres of pigment or a single mass [Southern). In lateral 

 view the body abrui)tly narrows to the anal funnel, whicli is 

 a flattened tube with a dorsal opening i)osteriorly. The 

 7nargin of the funnel is pai)illose postcrioily, Southern 

 describing the opening as projecting in four lobes, each 

 bearing a fusiform paj)illa. A long slender cirrus, nearly 

 twice as long as the anal funnel, arises from the ventral base 

 in front of the funnel. 



The feet occupy the upper and outer border of tlie ridges 

 made by the ventral longitudinal muscles. The setigerous 

 lobe is rounded, and bears superiorly the long subulate 

 cirrus in which at least one blood-vessel is present, then 

 a tuft of simple capillary bristles ; ventrally a similar tuft 

 of bristles and a small, somewhat clavate, ventral cirrus 

 [Souther7i). 



In the Scalibregmidse Asclerocheilus intermedius, De St. 

 Josepli, was dredged by Southern in Blacksod Bay and 

 other places on the West Coast of Ireland. It is a small 

 species, n easuring about 2 or 3 mm., the anterior end 

 being distinguished Ijy two rounded processes Mith a de- 

 pression between. The body is somewhat fusiform in outline, 

 slightly tapered anteriorly and abruptly so posteriorly. 

 Body apparently lias about twenty segments. So far as 

 seen, no ventral cirrus is present and no eyes *. 'i he venti ai 

 hooks of the second segment have a marked curve backward 

 (sickle-like) at the tip, and terminate in eharj), not attenuate, 

 ])oints. The upper bristles of the second segment arc capil- 

 lary, with finely tapered, long points. The posterior bristles 

 are* more elongate. Apparently tranverse rows of opaque 

 glands occur posteriorly in each segment. 



* The eyea are probably deep-seated, as in S. minvtus. Vide the
