148 Messrs. T. and A. Scolt on some 



the palm of the second gnathopods is finely serrate only on 

 the distal half, while the proximal half is even or nearly so 

 and bears a 'icvf minute setae. The postero-lateral angles of 

 the last epimeral plates of the metasome are also simply 

 angular, and not produced posteriorly into a tooth-like pro- 

 jection as in Am-philochoides odontonyx. 



Metopa robusta, G. O. Sars. 



A few specimens of this interesting species were dredged 

 this summer in deep water in the Moray Firth ; it was easily 

 distinguished by the structure of the gnathopods, the form 

 of the large fourth pair of coxal plates, and by the very 

 robust posterior pereiopods ; the posterior part of the raeros 

 of these pereiopods, and especially of the seventh pair, is 

 greatly developed. The contrast between the feeble and 

 slender first pair of gnathopods and the powerful second 

 pair is very marked in this species. 



So far as we know, the three Amphipods just referred to 

 do not appear to have been previously recorded as British. 



Additional Note. 



Cletodes monensis, I. C. Thompson. — In our paper in the 

 ' Annals and Magazine of Natural History ' for October last 

 we recorded the occurrence of this Copepod in the Moray 

 Firth, and in doing so we inadvertently called it Laophonte 

 monennis instead ot Cletodes moncnsis. 



Ste.phos minor ^ T. Scott. — This genus and species were 

 described and figured in the ' Tenth Annual Report of the 

 Fishery Board for Scotland (1892).' Dr. W. Giesbrecht, in 

 a })a])er recently published by him *, refers to this genus and 

 identifies it with tiie genus Mobianus described in his new 

 and great work on the Pelagic Copepoda of the Gulf of 

 Naples. He makes a few remarks on the question of 

 priority, and appears to be in doubt as to whether Stephos or 

 Mobianus was published first. As the result of personal 

 investigation and inquiry we are now able to say that we 

 quite agree with Dr. Giesbrecht as to the identity of the two 

 genera ; but the species from the Gulf of Naples is, we 

 think, different from that from the Firth of Forth, additional 

 specimens of which have been recently obtained by us. As
