V,. IV 1 THE HISTOBY OF ANIMALS. 77 



inhabits a shell like a snail. This animal never leaves its 

 shell, but remains in it, like the snail, and somct imcs stretches 

 out its tentacula. Let thus mueh be said about the malacia. 



CHAPTER II. 



1. OF the malocostraca, there is one genus, of carabi, 1 and 

 another, very like it, of astaci ; a these differ from the carabi, 

 which hare no claws, and in some other respects. There 

 is a third genus, of carides, 3 and a fourth, of carcini. 4 There 

 are more genera of carides, and of carcini ; for among the 

 carides are the cyphse, 6 the crangon, 6 and a small species, for 

 these never grow large. 



2. The family of carcini is more various, and not so easily 

 enumerated ; the largest genus is that called maia, 7 the next 

 to this the pagurus, 8 and the Heracleot carcini ; and, again, 

 those that live in rivers. The other genera are small, and 

 have not received any name. On the Pheuician coast there 

 are some that they call horsemen, because they run so fast 

 that it is difficult to catch them, and when opened, they are 

 empty, because they have no pasture. There is another 

 small genus like carcini, but in shape they resemble astaci. 



3. All these creatures, as I observed before, have their 

 hard and shelly coats on the outsides of their bodies in the 

 place of skin, the fleshy part is internal. Their under parts 

 resemble plates, upon which the females deposit their ova ; 

 the carabi have five feet on each side, including the claws ; 

 the carcini, also, have in all ten feet, including the claws, 

 which are last. Of the carides, the cypha have five on each 

 side ; those near the head are sharp, and five others on each 

 side of the stomach have flat extremities ; they have no 

 plates upon the under pa/t of their body ; those on the 

 upper part are like the carabi. 



4. The crangon is different, for it has, first of all, four 

 plates on each side, and, afterwards, three slight ones, con- 

 tinuous with those on each side, and the greater part of the 

 remainder of its body is apodal ; all the feet are directed 

 outwards to the side, like those of insects ; but the claws, 

 in those that have them, all turned inwards. The carabus
