Gf eus , Amphitoe. — Leach.

Amphitoe rubricata. — Montagu, Lin. Trans., ix, p. 99. — Bate and 

 Westwood, p. 418. 



The adult is colored a brilliant crimson with large blotches of 

 white. When young the animal is a yellowish green with minute 

 red spots and a few white blotches. 



The animals of this subdivision live in homes of their own 

 construction. This species makes one by collecting stray material 

 round some chosen nook, which it binds together with an ex- 

 quisitely delicate web. We have not been able to discover how 

 this web is secreted, whether by the mouth or some special 

 organ. 



It is tolerably common in a few fathoms of water or on shores, 

 but the first we ever saw were dredged in Plymouth Sound ; of 

 more brilliant a colour than any paint we could prepare to repre- 

 sent it. 



Amphitoe vittorina. — Spence Bate, Cat. Amph B. If. — Bate and 

 Westwood, p. 422. 

 Common on stony beaches associated with Gammarus, being 

 larger, it may readily be detected as a " Triton amongst the 

 minnows." 



Genus, Sunajvipiiitoe. — Spence Bate. 



Cat. Amph. B. M. — Bate and Westwood, p. 429. 



Like Amphitoe, cxcejri that the Telson or extremity of tail ends 

 in a hook. 



Shxa.mphitoe hamulus. — Spence Bate, Cat. Amph. B. M. — Bate 

 and Westwood, p. 430. 

 A specimen of this species lias been sent to us from Penzance.
