Genus o. Metopella, G. O. Sars. 



First gnathopods not subchelate. Basos of last three 

 perseopods not expanded behind and almost or quite linear in 

 form, and the meros only very slightly produced behind.

Bab. Taken in company with my late friend Dr. D. Robert- 

 son in 1888 off Fairland Point, Isle of Cumbrae, in 20 fathoms: 

 Mus. Nor. Deep water off May Island, in the Firth of Forth, 

 and in the Moray Firth ( T. 8.). 



Bistrib. West Norway (G. 0. Sars) : Mus. Nor. Hansen 

 records it with doubt from Greenland. 



Genus 4. Metopina, gen. nov. 



I institute this genus to receive three aberrant forms of 

 Metopa, in which the first gnathopods are not subchelate, and 

 have the hand long and very slender, and the terminal joint 

 very minute, flattened, not nail-formed. The second gnatho- 

 pods are very robust; the last peraopods have the posterior 

 projection of the meros well and often enormously developed. 

 The type species is Metopa pahnata, Sars ; the others are 

 M. clypeata, Kroyer, and M. robusta, Sars. 



108. Metopina robusta, G. 0. Sars. 



1892. Metopa robusta, G. O. Sars, (142) p. 270, pi. xcvi. fig. 1. 

 1894. Metopa robusta, Thomas Scott, " Some new and rare Crustacea 

 from Scotland," Ann. & Mag. Nat. Hist. ser. 6, vol. xiii. p. 148. 



Bah. Firth of Forth, 1884 (Br. J. R. Henderson): Mas. 

 Nor. In this same locality Mr. Scott subsequently found 

 three specimens, and first recorded the species as British. 

 He has since also found it in the Moray Firth. 



Bistrib. Varanger Fiord, East Finmark, 125-150 fathoms, 

 1890 (A. M. N.) : Mus. Nor. Sars's specimens were from 

 Bejan, in the outer part of the Trondhjem Fiord, and 

 Hammerfest, West Finmark ; in both places in 30-50 fathoms 

 among Hydroids. Tromso (Schneider-).
