I. '08. 108 



thinly sprinkled with faint red chromatophores, often more 

 numerous proxinially. The outer maxillipedes and pereiopods 

 are banded with scarlet, red, or pale red, sometimes with an 

 admixture of very small golden yellow chromatophores. The 

 red colouring is in many cases most strongly pronounced at 

 the bases of the third and fourth pereiopods. The telson and 

 uropods are pale, with a broad transverse band of red across 

 the middle. The eggs are green. 



Many colour varieties doubtless occur. Kinahan mentions 

 rose pink, green and cobalt blue forms, and others are de- 

 scribed by Smith (1879). 



General distribution. — Spirontocaris pusiola has been re- 

 corded from the Mm^man coast (Birula), Spitzbergen 

 (Sars), Iceland (Sars), E. Finmark to S. Norway (Norman 

 and Sars), Sweden (Goes), Denmark (Meinert), Holland and 

 North Sea generally (Metzger and Norman). In the West 

 Atlantic it has been found between Connecticut and Nova 

 Scotia (Smith), while in the Pacific it has occurred in the 

 Bering Sea and off Alaska (Eathbun). 



Off the English coasts this species has been once recorded 

 in the south, from Plymouth (Spence Bate). It is known 

 from the Lancashire coast (Piel, Walker) and in the east it 

 is recorded from the coasts of Norfolk (Metzger) and Nor- 

 thumberland (Norman) ; there can be little doubt that it is 

 far from scarce in both east and west. In Scotch waters it 

 has been found on several occasions in the Firth of Forth and 

 off Aberdeen (Scott) and has also been taken near the Ork- 

 neys (Fleming) and Shetlands (Norman). 



Irish distribution. — This species is by no means uncommon 

 on the east coast trawling grounds between Dublin and the 

 Isle of Man , but has not as yet been found further south than 

 Bray Head, Co. Wicklow. It has been recorded by Kinahan 

 from Bangor, Co. Down, and from Whitehead and the Gob- 

 bins, Co. Antrim. Off the north coast it has been found on 

 one occasion in Eathlin Deep, Co. Antrim. In the west S. 

 pusiola seems to be very scarce ; it has been found in Broad- 

 haven, Co. Mayo, and there is a specimen in the Dublin 

 Museum which was caught in Bantry Bay. In the south the 

 species has not so far been observed. 



Vertical range. — In the Irish Sea S. pusiola is most fre- 

 quently trawled in depths exceeding 15 fathoms, but it has 

 been found in shallower water up to 4 fathoms. In Eath- 

 lin Deep the species was taken in as much as 115 fathoms. 

 Smith (1879) records it from between low^-water mark and 

 105 fathoms on the E. coast of N. America, while in the 

 Pacific it has occurred between 6 and 159 fathoms (Eathbun).
