British Isopoda Chelifera. 333 



the late Mr. D. Robertson sent to Spence Bate, which that 

 author at first thought a distinct species and named in MS. 

 T. hirticaudatus, may really have been that now known as 

 T. Chevreuxi. 



10. Tanais Dulongii (Audouin). 



1866. Tanais Dulongii, Bate & Westwood, (1) vol. ii. p. 129. 



This species is at present unknown to me, and I am 

 unable to throw any light upon it. 



Bate and Westwood write : — " The only individuals which 

 we have seen were sent to us from Polperro by Mr. Laughrin." 

 In the " Last Report of Dredging among the Shetland Isles " 

 I recorded this species from " St. Magnus Bay, rare." I 

 have now searched in vain in my collection for the specimens, 

 and can neither find it or any other Shetland form which 

 could have been confounded with it. I know that many of 

 my Tanaidse were years ago dried up, and this form was 

 probably among them. 



Genus 2. Leptochelia, Dana.

Hob. The specimens described by Bate and Westwood were 

 found by me among Zostera between tide-marks in Belgrave 

 Bay, Guernsey. Since the publication of that work it has 

 been recorded from Sark {Kcehler) and Jersey {Sinel and 

 Hornell). 



Distrib. I have procured it at Naples. Gourret records it 

 from Marseilles ; Sars from Trieste, Spezia, Messina, and 

 Syracuse ; and Chevreux and Dollfus also from many places 

 in the Mediterranean. The former of these has proved its 

 range on the Atlantic coast from Brittany to Senegal. 

 Azores (Th. Barrois). Kroyer's type specimens were from 

 Madeira.
