66 AMPHIPODA NORMAI.IA. 



shire coast. I have had specimens sent to me from the following 

 localities: — Falnioiitli and Tenby, Mr. W. Webster; Penzance, Mr. 

 Hanis and Mr. G. Barlee ; from the Moray Frith, Rev. G. Gordon ; 

 from Skye and the Slietlunds, Mr. G. Barlee ; Plymouth, Mr. Howard 

 Stewart. In Mr. Thompson's Irish Collection it is recorded as 

 prociired from Sligo and Belfast Bay. 



One specimen I obtained from the traw'lers is marked all over 

 with red spots. The palm on the propodos of the second pair of 

 giiathopoda differs from the normal form in being slightly crenulated ; 

 bnt I could distinguish no consistent feature that warranted a sepa- 

 ration from the present species.

Specimens have been sent to me from the coast of Northumberland 

 by Mr. Joshua Alder, from Banft' by Mr. Edward, and from Macduff

 near the Eddystone Lighthouse, Plymouth. 



A specimen, varying from the tj-pe in having the pahn on the 

 propodos of the second pair of gnathopoda occupying scarcely more 

 than half of the inferior margin, has been sent to me by my friend 

 Mr. J. Gwynn Jeffreys, baring been found by him, on the coast of 

 Piedmont, on the shore. None of the British specimens have been 

 taken in less than 10 fathoms.
