REPORT ON THE AMPHIPODA. 1641 



" With reference to the food of the east coast herring," the authors say, " it may be stated 

 generally that the relative frequency of Hyperia and [the Schizopod] Nyctiphanes depends 

 on the month during which the fish were captured. Hyperia is extremely abundant during 

 January and February, and the stock then gradually diminishes, or at any rate the herring 

 do not feed on this form to such a great extent after that time." But as the Hyperix 

 become rare, the stock of Nyctiphanes increases. " The quantity of the one appears to be 

 inversely proportional to that of the other."

The Amphipoda occupy pages 67-127 (pp. 296-356 of the Bulletin itself), 1 and a part of 

 pages 189, 190. The "Index bibliographique des ouvrages cites" extends from page 167 

 to page 184. In the classification of the Amphipoda Boeck's latest work is followed ; no 

 new species are recorded or described ; some brief notes are given on some of the known 

 species, of which sixty-four are enumerated, with an elaborate synonymy, the discussion of 

 which would involve too much repetition of remarks already made in earlier notices.

Crustaces Amphipodes nouveaux dragues par YHirondelle, pendant sa campagne

 Paris, 1887. 15 pages. 



Off Cape Finistere, at a depth of 510 metres, the Hirondelle obtained specimens of " Nicippe 

 tumida Bruz.," " Ampelisca anomala G. O. Sars," and " Urothoe ahbreviata G. 0. Sars," 

 and the following new species, of which descriptions are given — (1) Opis hispana, (2) 

 Harpinia excavata, (3) Amphithopsis grand imana, (4) Tritropis Grimaldii, (5) Ampelisca 

 uncinata, (6) Ampelisca spinimana, (7) Byhlis Guernei, (8) Podoeeropsis abyssi. Of these 

 the species numbered 1, 2, 5, and 8 are said to be without eyes. Opis hispana should be 

 called Opisa hispana, the preoccupied Opis having been changed by Boeck, and Tritropis 

 grimaldii should be called Rhachotropis grimaldii, S. I. Smith having substituted Rhacho- 

 tropis for the preoccupied Tritropis. In Podoeeropsis abyssi there is a rudimentary secondary
