OPHELIIDAE

Family OPHELIIDAE 



Genus Ammotrypane, Rathke 



Ammotrypane breviata, Ehlers. 



Ehlers, 1913, p. 523, pi. xxxix, figs. 1-7. 



St. 167. 20. ii. 27. Off Signy Island, South Orkneys. 60° 50' 30" S, 46° 15' 00" W. 244-344 ^• 

 Gear N 4-T. Bottom: green mud. Nine specimens. 



Remarks. The largest example measures 34 mm. by 2 mm. The number of chaetigers 

 is 28. The specimens correspond exactly to the description and figures of this species. 

 They have gills on every chaetiger except the ist and the last four modified chaetigers. 

 The anal cylinder is very faintly and irregularly ringed, and its dorsal peak is much 

 more prominent than the ventral. 



Genus Travisia, Johnston 

 Travisia olens, Ehlers. 



Ehlers, 1897, p. 98, pi. vi, figs. 162-163. 

 Benham, 1927, p. 123. 



St. 51. 4. V. 26. Off Eddystone Rock, East Falkland Island. From 7 miles N 50° E to 7-6 miles 

 N 63° E of Eddystone Rock. 115 m. Gear DLH. Bottom : fine sand. Two specimens. 

 Sparrow Cove, Port William, East Falkland Island, i m. Net RM. One specimen. . 



Remarks. The terminal segments of these specimens are T3mm 

 difficult to count accurately, but there are between 29 and 

 31 segments. It is also not at all easy to determine the 

 segment on which the posterior or abdominal region, dis- 

 tinguished by the lateral eminences, begins, but I estimate 

 15-16 posterior segments. The body tapers gradually down 

 to the anal cylinder (Fig. 66) which is equal in length to 

 the last two segments. 



Benham (loc. at.) discusses at length the relation of 

 this species to T. kerguelensis, Mcintosh. I give my views 

 on this matter in my remarks on the latter species, 



Travisia kerguelensis, Mcintosh.

 specimens. 



St. 157. 20. i. 27. 53° 51' 00" S, 36° 11' 15" W. 970 m. Gear DLH. Bottom: diatomic ooze, 

 stones and fine sand. One specimen. 



St. 159. 21. i. 27. 53° 52' 30" S, 36° 08' 00" W. 160 m. Gear DLH. Bottom: rock. Three
