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 

 stones.
