The Schizopoda and Isopoda collected by the 

 '• Huxley " from the north side of the Bay of Biscay, 



in August, 1906.

I AM indebted to the courtesy of Dr. Allen for the opportunity of 

 examining the collections of these two orders of Crustacea in the 

 Huxley's material. 



None of the species are new to science, and but few of them present 

 any features worthy of remark. The chief interest of the collection 

 lies in its bearing on the known geographical distribution of the 

 species captured for, out of a total of twenty-eight, no fewer than 

 sixteen are recorded for the first time from localities south of the 

 British Islands, while only eight of the species have previously been 

 recorded from the Bay of Biscay. The ba thy metrical range of five 

 of the species recorded has been considerably increased by this 

 material. 



A comparison of the following lists with those for the same orders 

 collected by the Caudan expedition, reveals little that is common 

 to the two, the explanation of which is probably that the Caudan 

 was working in much deeper water and considerably south of the 

 area explored by the Huxley. The results of the work done by 

 the Hirondelle and the Travailleur and Talisman in the Bay of 

 Biscay are not available for the orders now under consideration. The 

 only other expedition which has worked in the Bay is the Research, 

 but as that dealt entirely with plankton, the results are not strictly 

 comparable with those of the Huxley.
