Genus 4. Urothoe, Dana. 



Stebbing^ published an elaborate paper " On the Genus 

 Urothoe and a New Genus, Urothoides " (Trans. Zool. Snc. 

 vol. xiii. 1891). He examined the specimens then in my 

 collection, and I follow here his lead, but think that some of 

 the species are of doubtful value ; but, on the other hand, I 

 can still less acquiesce in Delia Valle's views, who not only 

 unites the whole of the forms here included, but adds U. t'rros- 

 trafa, Dana, U. abbreviata, Sars, and U. Poucheti, Chevreux. 

 Rut on the question what characters suffice for specilic distinc- 

 tion naturalists will always find it necessary to agree to differ. 



54*. Urothoe pulchella (A. Costa). 



1857. Egidia pulchella, A. Costa, " Orost. Amfip. Regno di Napoli," 

 Mem. d. R. Accad. d. Sci. di Napoli, vol. i. p. 190, pi. iv. figs. 3 a-g. 



1887. Urothoe pnlchella, Stebbing, /. c. p. 11, pi. iv. a.

 pl.x.xxvi. figs. 1-18, pi. Ix. figs. 11, 12. 



Hah. " Several specimens of this Urothoe have been ob- 

 tained in the Firth of Forth ; it is a smaller species tlian 

 U. marina'' [T. Scott, " Addit, to Fauna of the Firth of 

 Fourth," Fourteenth Rep. Fish. Board of Scotland, 1896, 

 p. 159). This is the only notice of it as a British species. 



Z)?V<ri&. Naples {A. M. N.) ; West France {Chevreux). 



I was struck with the lovely rose-colour of the species (or, 

 at any rate, of the males) when I took them (see Delia Valle, 

 pi. V. fig. 8).
