Habitat. — Not uncommon in sandy bays between 

 tide-mark. I have taken it by the sieve in the 

 sands at Irvine and Fairlie, Ayrshire ; Lamlash 

 Bay, Arran ; Karnes Bay, Fintry Bay, and Balloch 

 Bay, Cumbrae ; and off the same shore by the 

 surface-net after sunset. Those taken by the sur- 

 face-net are mostly males (=elegans), and often 

 have a beautiful pink blush along the inferior 

 portion of the pleon. Some of these were kept in 

 water for a night, and in the morning they were 

 all found floating on the surface, showing little 

 inclination to attach themselves to bits of sea-weed 

 or other floating objects, as Atylus Sicammerdamii 

 and Dexamine spinosa do. The females swim briskly 

 through the water, and can burrow into the sand 

 with great speed. They are of a yellowish-brown 

 colour, in some cases darker along the back. The 

 young have two longitudinal bars along the dorsal 

 region that are well seen before they leave the 

 parent. The eyes of the adult are dark purple, 

 thinly studded, as it were, with white points. 



This species has also been taken in Dublin Bay 

 by Professor Kinahan ; in trawl-refuse from near 

 to Eddystone Lighthouse by Messrs. S. Bate and 

 Westwood; and in from GO to 70 fathoms near 

 Outer Haaf, Shetland, by the Rev. A. M. Norman 

 and Dr. J. G. Jeffreys.
