72 THE ZOOLOGIST. 



Its carapace is strongly segmented laterally, the upper margins 

 of each fold being fringed with setae, and, towards the rostrum, 

 with spines also ; the lateral margins are also strongly spinous, 

 the spines pointing forwards in the same direction as the rostrum, 

 which latter is formed of three stout and sharp points. The 

 antennae are fine, long, and have the basal joint spinous. Eyes 

 kidney-shaped. The anterior pair of legs equal and proportionate, 

 densely covered with spines and setae, the forceps being beautifully 

 fringed with the latter ; the next three pairs also spiny and ter- 

 minating with a powerful claw; last pair rudimentary. 



The colour of this handsome species is usually a warm red- 

 dish brown, with decided markings of a bright blue, which, 

 however, should be seen in life to be fully appreciated. 



Prof. Bell's graphic description of the rapid backward jerking 

 (for it can scarcely be termed swimming) of this species we can 

 fully endorse, from observations both in a state of nature and in 

 captivity, and it is certainly remarkable to find an animal with 

 anterior eyes of such development whose movements are of such a 

 retrograde character, so to speak, as those of Galathea strigosa. 

 Of course, when safely landed in its burrow, or crevice, its eyes are 

 of great service in watching its prey or its enemies ; but as to its 

 general movements in the water, they are decidedly in a direction 

 where these organs of vision would be of but little service. 



The ova of this species are small, of a golden colour, and 

 connected in groups, of great beauty when examined by the 

 microscope. As regards the zosea, we may refer our readers to 

 the woodcut in Bell's work ; the filamentous tail is very similar 

 to that of the zosea of Lithodes mala, another crustacean of the 

 division Anomoura. 



G. strigosa is a fairly distributed species, inclining to southern 

 waters ; it is common on our south-west shores and in the Channel 

 Islands, though it is found also in our northern seas. At Wey- 

 mouth it is called the " Spanish Lobster," possibly on account of 



its bright colours.
