DE. G. n. FOWLEE — BISCATAN PLANKTON 



when adult; and the larcjest of these specimens was only 3'75 mm. The adult has 

 already heen recorded * from an open deep net (409 to fathoms) in the Bay of 

 Biscay. Unfortunately the small number of captures on our cruise does not materially 

 increase our knowledge on this point, but does extend the epiplanktonic distribution 

 of the young considerably southwards, Valentia being the most southerly point hitherto 

 recorded to my knowledge. 



EUTHEMISTO COMPRESSA (Goes). 



For the distribution of this form, long supposed to be subarctic, compare Proc. Zool. 

 Soc. 1903, i. p. 127, and Vosseler, ' Amphipoden der Plankton-Expedition,' p. 86. 



Primno macropa, Guerin. 



This seems to be a nearly cosmopolitan species, at any rate if the synonymy referred 

 to above by Mr. Stebbing be accepted. 



Brachyscelus mediterranetjs (Glaus). 



This widely-distributed species Avas described by Glaus from Naj)les, and recorded by 

 the ' Ghallenger ' at various localities in the North and South Atlantic, always at the 

 surface. By the ' Hirondelle,' in addition to two surface-captures, it was taken with 

 the "filefc a gouvernail'' from 710 and 1201 fathoms, by the 'Oceana' in open nets 

 lowered to various depths. 



Previovis records of the remaining species are most easily placed in tabular form (p. 52). 



The following table (p. 51) shows the occurrences of the various species of Amphipoda 

 expressed as serial numbers in the list of species. The first three hauls are with the 

 mesoplankton trawl, the remainder with tow-nets ; "non-comparable" hauls are marked 

 with a f .
