"Well-wooded districts in England and Wales are the favourite 

 haunts of this handsome spider, which, even in the adult state, 

 varies greatly in colour. The Ocyale murina of M. Koch, de- 

 scribed by that arachnologist as a distinct species, is merely the 

 female of Dolomedes mirabilis after she has exercised her parental 

 functions. In June the female constructs a globular cocoon of 

 dull yellow-coloui'ed silk of a compact texture and rough exterior 

 surface, measui-ing j%ths of an inch in diameter, in which she 

 deposits between 220 and 240 eggs of a spherical form and dull 

 yellow colour, not agglutinated together. This cocoon, for which 

 she manifests a strong feeling of attachment, is carried underneath 

 the sternum, and retained in that situation by means of the falces* 

 and palpi, additional support being usually supplied by silken 

 lines connecting it with the spinners ; this latter circumstance, 

 it will be perceived, furnishes a new link in the chain of analogies 

 which connect the genus Dolomedes with that of Lycosa. When 

 the young are about to quit the cocoon, the female spins a large 

 dome-shaped web among grass or low bushes, under which she 

 retires with her treasure, and her progeny, on being extricated 

 from their silken envelope, cluster together on hnes spun by 

 themselves beneath the dome, where they remain till they are 

 capable of providing for their own sustenance.

 * The organs of spiders, improperly denominated mandibles, as they are 

 situated above the labrum, and, consequently, form no part of the oral ap- 

 paratus, I have proposed to name /aZces.
