TRAVISIA. 25 



Ophelina Kukenthalt, Mcintosh, 1908. 



Specific Characters. — Head pointed, a slender clavate papilla projecting beyond it. 

 Body 25 mm. long, resembling Polygordins, tapered a little anteriorly and posteriorly, 

 rounded dorsally, and grooved ventrally. It diminishes slightly posteriorly, and then 

 abruptly narrows to a short, cylindrical, caudal process, with a smooth edge and no 

 bristles.

 1908. Ammotrypane (Ophelina) Kiikenthali, Mcintosh. Ann. Nat. Hist., 8 ser., vol. i, p. 387. 



Habitat. — Dredged at 795 fathoms in the ' Porcupine ' Expedition of 1870. 



Head pointed, with a slender clavate papilla projecting beyond it. No eyes in the 

 preparation. Nuchal organs probably present, though they are not distinct in the spirit- 

 specimens. 



Body about 25 mm. in length (in spirit) and having the aspect of a Polygordius, 

 tapered a little anteriorly and posteriorly, rounded dorsally, and grooved ventrally. The 

 ventral longitudinal muscles run on each side from the region of the mouth to the base of 

 the caudal process, and have the usual lateral groove above them, but, so far as observed, 

 neither bristles nor pigment-specks are present. The mouth occupies the ordinary 

 position on the ventral surface a short distance behind the tip of the snout. The body 

 slightly diminishes posteriorly, then somewhat abruptly narrows to the short cylindrical 

 caudal process, which presents a smooth edge posteriorly. In one of the examples the 

 terminal edge is oblique, in the other it is rounded, but, as both examples appear to have 

 been more or less dried, uncertainty remains on this point. 



The slender, smooth, glistening body and the absence of bristles, cirri, and papillae 

 on the caudal process are features of moment. 



Hansen 1 , in his original account of a species of Ophelina, gave no description of the 

 genus, and associated it with another species which differed in the form of both the head 

 and the caudal region. Both came from South America. 



Genus LXXXV. — Teavisia, Johnston, 1840. 



Body short, spindle-shaped, without a ventral sole or ventral groove; segments 

 generally three-ringed ; posterior segments two-ringed. Thicker posteriorly, with on 

 each side on broader segments double lateral processes (feet) without papillae. Two tufts 

 of bristles on each side. Branchiae occur on the anterior segments, but disappear 

 posteriorly.
