the ground, and generally congregates in numbers. It feigns 



death, but does not roll itself up in the least. 



Philotjgria bosea. — Koch, Beutsch Crust., 22, 16. — Bate and 



Westwood, p. 460. 

 ' It is tolerably abundant in gardens in Plymouth. This is the 

 only habitat yet known in England. We have little doubt but 

 that it only has to be looked for in Cornwall to be found. It is 

 of a pretty rosy colour, and may be found in garden pots and 

 crevices of the yards. 



Gentts, Onisous. — Zinncetis. 



Head with large lateral lobes. Second antennae eight- jointed ; 

 second joint detailed at the base. Tail appendage imbranched 

 short. 



Oniscus ASELLtrs. — Lin. Syst. Nat., ii, p. 1061. — Bate and West- 

 tvood, p. 468. 



Common throughout England, Scotland, and Ireland, under 

 decaying vegetable and animal matter. Common near the sea. 



Genus, Porcellio. — Latrielle. 



Second antennee seven jointed. Tail appendage with outer 

 branch trigonate, exposed ; inner, small and concealed.

 — Bate and Westivood,p. 475. 



This species runs with agility, and partially rolls itself into a 

 ball when alarmed. It has been observed feeding on living 

 caterpillars ; frequenting moist places where decaying vegetation 

 is found, also among sea-weed with Ligia. It is partial to grow- 

 ing vegetables, and enjoys ripe fruit. Common throughout 

 England and Ireland. 



I have little doubt but that most, if not all the British species 

 might be found in Cornwall if they were looked for. 



Genus, Armadillo. — Latrielle. 



Very convex. Capable of rolling itself into a ball. Second 

 antennae seven- jointed. Tail appendages not reaching beyond 

 the margin of the body. 



Apmadillo vuLGATiis. — Latrielle, Hist. Nat. Crust, et Ins., vii, p.
