(Kemp) ; Atlantic (Stebbing [?] ; and Monod as the van sulcirostris 

 Kemp). Although not previously found east of the Marquesas or Hawai- 

 ian Islands, it is here recorded from La Libertad, Ecuador, where 2 speci- 

 mens, male and female, were dipped from the surface by Mr. Fred 

 Ziesenhenne while using an electric light off the ship's gangway, January 

 20, 1933 (Hancock Exped. Sta. 17-33). 



The "foot long" specimen which Stebbing*^^ received from Antigua, 

 B.W.L, has all the earmarks of a large specimen of L. scahricauda, espe- 

 cially as regards the spinulation of the hind margin of the 5th abdominal 

 somite, and both anterior and posterior margins of the 6th, in the mar- 

 ginal armature of the telson, and "in not having the rostral point pro- 

 duced." Whether the surface of the telson was scabrous or not is not 

 mentioned. Some specimens of L. scahricauda have the surface of the 6th 

 abdominal somite almost wholly smooth except for some low, not particu- 

 larly conspicuous, granulations toward either posterior lateral portion of 

 the dorsum, and the telson not conspicuously roughened, although granu- 

 lated for a considerable part of its surface like posterior parts of the 6th 

 somite; the median raised area of the telson is always smooth, even in 

 otherwise very scabrous specimens of scahricauda. I am inclined to think 

 that Stebbing's specimen is a rather smooth-telsoned specimen of scahri- 

 cauda instead of one of L. maculata. The marginal spinulation of the 5th
