Canon A. M. Norman on British Amphipoda. 43 



Hah. The specimens I have seen of this species are all 

 from the eastern side of our island. That figured is one of 

 those from Cullercoats, Northumberland, which Bate and 

 Westvvood recorded under the name Montagua clypeata. 

 Other specimens in my collection are from St. Andrews 

 [Professor M'Intosh) and Aberdeen (Mr. R. Dawson). 



I have thought it best to figure a Cullercoats specimen, 

 since it was one of these which was recorded by Bate and 

 Westwood. My St. Andrews example is, however, more 

 mature, and, agreeing in all other respects, differs somewhat 

 in the form of the hand of the second gnathopod, which is 

 somewhat longer in proportion to the breadth, nearly twice 

 as long as the greatest width ; the palm &c. is as in the 

 Cullercoats example. 



This species is nearest allied to M. rubrovittata, from which 

 it may be easily distinguished by the totally different form of 

 the first gnathopod (fig. 5, first gnathopod of M. rubrovittata) , 

 by the absolutely transverse palm of the second gnathopods, 

 and by differences in the last peraeopods. 



My friend the late Dr. D. Robertson, in the appendix to 

 his first report (p. 91, separate copy), recorded " Metopa 

 ctypeata" from Cumbrae. It is probable that the Amphipod 

 found by him was Metopa rubrovittata, since I have on two 

 occasions, in 1854 and in 1885, taken that species at Cumbrae. 



Dr. Hoek has described from Holland a Metopa nearly 

 allied to M. rubrovittata under the name Metopa Normani 

 (Hoek, " Crustacea Neerlandica, II.," Tijdsch. der Nederl. 

 Dierkundige Vereen. ser. 2, vol. ii. p. 21 (separate copy), 

 pi. vii. figs. 5 and b') ; but it appears to be more closely 

 allied to M. rubrovittata than the species which I have here 

 described.
