TEREBBLLID^. 



Amphitrite robusta Johnson. 



Amphitrite robusta Johnson, Proc. Bos. Soc. Nat. Hist., XXIX, pp. 425, 426. 

 This species appears to be quite abundant in the Gulf of Georgia and 

 as far north as Naha Bay, Behm Canal. It reaches a larger size than 

 is indicated by Johnson, sometimes exceeding 140 mm, in length and 

 18 mm. in diameter, the greatest niunber of segments being 83. The 

 divisions of the branchiae are often longer than figured by Johnson, 

 whose figure of the uncinus also is somewhat foreshortened. The 

 number of setigerous somites is constantly 17, as stated by Johnson. 

 Some of the specimens bear short cirri or papillae beneath the setas of 

 some of the anterior segments. This is probably a secondary sex 

 character, but this could not be ascertained with certainty.

Lanice heterobranchia Johnson. 



Lanice heterobranchia Johnson, Proc. Bos. Soc. Nat. Hist., XXIX, p. 427. 

 The original description is based upon a single specimen which was 

 stated to have no eyes. All of several specimens in the present collec- 

 tion possess very numerous deep brown eyes arranged in a compact
