Bottom: grey >mm-. ImiYi" O-L Remarks. One specimen in poor condition and its tube. The specimen measures 9 mm. for the body and 4 mm. for the gills. There are eight thoracic and fifteen abdominal chaetigers. There are no colour markings. The condition is such that the example can only be doubtfully attributed to a species. There appears to be a membrane extending for about a third the length of the gills: the head region and collar are too much damaged for description. Dorsally there are two large prominent glandular pads, running from the 3rd chaetiger to the base of the head region. I take this to be a nuchal gland, and the dorsal lappets of the collar appear to be fused with it. The thoracic bristles consist of winged (Fig. 85,<7) and spatulate bristles, and the thoracic hooks (Fig. 85, b) have very long downwardly directed manubria and crests of four to five rows of denticles; the abdominal bristles are slender and capillary without borders; the abdominal hooks (Fig. 85, c) are avicular with crests of eight rows of teeth. The chaetae of this specimen agree with Benham's description and figures closely except in one particular: in this specimen, the end of the manubrium of the abdominal hooks turns back sharply at right angles to the rest of the shaft and is not gently curved backwards as it is in Benham's fig. 106. Ehlers'J', caeca from Kerguelen is briefly described without figures, but is probably synonymous with Benham's species. As already said, I can only doubtfully assign the present specimen to a species. The tubes are incrusted with sand grains and small black Please note that these images are extract
