dorsal part of the carapace. The rostrum is more or less 

 thickly sprinkled with a pigment uniform with the general 

 colouring, but the dorsal margin is often quite white. The 

 eyes are greyish black. The antennules and antennae are pale 

 with reddish mottling" on the peduncle ; the antennal scale is 

 more or less thickly mottled with red, and occasionally ex- 

 hibits a white patch neai' the apex. The outer maxillipedes 

 and first pair of pereiopods are dark red ; the remaining pairs 

 of legs are paler red with whitish bands. The telson and 

 uropods are, as a rule, paler than the general colouring, and 

 are in some cases quite transparent. 



General distrihution . — Spirontocaris spirms appears to have 

 a circumpolar distribution. It has been recorded from the 

 Murman coast (Breitfuss), from Spitzbergen (Kroyer, Sars, 

 etc.), from the east and wTst coasts of Greenland (Kroyer, 

 Ohlin, etc.) from Grinnell Land to 81° 44' N. lat. (Miers), from 

 Labrador (Packard) and south to Massachusetts Bay (Smith), 

 from the Bering Sea and Straits (Stimpson and Eathbun), 

 and from Alaska southwards to Lituva Bay (Eathbun). It is 

 also know^n from west Norway and Finmark (Sars), from Ice- 

 land (Appellof), from Sweden (Goes), from Denmark 

 (Meinert) and from the vicinity of Kiel. 



The variety Lilljehorgi does not extend as far north as the 

 type, but seems to replace it to a great extent in the more 

 southern localities. 



In British waters this species has been recorded from the 

 Shetlands (Norman), from both east and w^est coasts of Scot- 

 land (Leach, Scott, etc.), from the Northumberland coast 

 (Norman), off Norfolk (Patterson), off the Isle of Man (Bell) 

 and near Plymouth (Sp. Bate). The majority of these records 

 refer to the variety.
