found on the South Coast of Devonshire, 101 



body behind the snout, placed two forward, two backward, 

 and appear under a microscope strongly reticulated; the tuber- 

 cle on which they are seated, verrucoses on the back between 

 the hinder pair of legs is an erect cylindric tubercle, which in 

 some point of view might be mistaken for a tail; the summit of 

 this is furnished with two minute spines : legs long, slender, 

 spinous. 



The tubercle, with the eyes, is represented at fig. 7* a.; the foot 

 at b. 



Length of the body a quarter of an inch. 



Colour rufous-brown. 



The female is furnished with a pair of long jointed appen- 

 dages, which originate at the fore part of the thorax, and turn 

 underneath, as described by the figure. 



The use of these antennae-like members is'for holding and car- 

 rying about their eggs. This sexual distinction in most, if not 

 in all, of the marine species of Phalangium does not appear to 

 have been noticed as such ; and for want of this knowledge the 

 same species have been differently described. These female ap- 

 pendages are very conspicuous both in Phalangium Balanarum 

 and Grossipes, and are frequently found holding a quantity of 

 eggs agglutinated to each. 



This might have been referred to P. hirtum of Turton, but the 

 want of the four palpi prevents it from being placed in his di- 

 vision of Nymphion.
