SERPULIDAE 209 



Genus Vermiliopsis, Saint- Joseph 

 Vermiliopsis notialis, n.sp. 



St. 14S. 9. i. 27. Off Cape Saunders, South Georgia. From 54° 03' S, 36" 39' W to 54° 05' S, 

 36° 36' 30" W. 132-14801. Gear OTL. Bottom: grey mud and stones. Two specimens. 



Description. Along and across a Cidarid spine is a number of small Serpulid tubes, 

 in contact all their length with the substratum. They have large peristomes and three 

 parallel toothed crests, recalling those of the Mediterranean V. miiUicristata. Unfortu- 

 nately I was unable to extract a worm from them in any but a very poor condition. The 

 measurements are about lo mm. by -5 mm. Owing to the bad condition I cannot with 

 certainty discover the number of thoracic chaetigers. There are probably seven, the 

 usual number for the genus. I am also unable to give an account of the collar and 

 thoracic membrane. A thoracic membrane is at any rate present. Each branchial lobe 

 (Fig. 87, a) has six rather short filaments, which are adherent and have the barbules 

 continued to the tip (Fig. 87, b). The opercular peduncle has neither barbules nor 

 wings. The operculum itself (Fig. 87, c and d) is a vesicular body, surmounted by a 

 long cone ending in one example in a cup-like disk. The cone is covered with long 

 chitinous spines except for a triangular area running up its outer face. 



The I St chaetiger has limbate bristles (Fig. 87, e) and fine capillary bristles (Fig. 8y,f) 

 with a denticulated edge. The remaining thoracic notopodia have similar bristles, and 

 from the 3rd chaetiger backwards a number of Apomatiis bristles (Fig. 87, g) in 

 addition. The thoracic hooks (Fig. 87, //) have 10 to 12 teeth of which the basal is far 

 the most prominent: this tooth is not excavated. The abdominal hooks are similar in 

 form, but smaller. The ventral abdominal bristles (Fig. 87, i) are geniculate, and in the 

 posterior abdominal segments there are a number of simple capillary bristles (Fig. 87, k). 

 I figure a portion of a tube (Fig. 87, /). 



Remarks. The description of this species must remain incomplete until the acquisition 

 of more and better material. The operculum with its chitinous spines seems to be charac- 

 teristic. In fact, under the present system of using rather wide variations in the oper- 

 culum as generic differentials, it might justify the establishment of a new genus. On 

 the other hand, in all characters except the operculum, the species agrees with Ver- 

 miliopsis ; and the reduplication of Serpulid genera based on differences in the operculum 

 alone is to be deprecated.

Remarks. I believe these examples to be conspecific with the specimens from 

 Annobon attributed to Gravier 's species by Augener. The operculum (Fig. 88, a) is,
