run so fast that it is not easy to overtake them.* He also 

 was well acquainted with more than one kind of hermit- 

 crab, and speaks of its living in different kinds of shells.! Of 

 the remaining crabs referred to by Aristotle there is one 

 which can be fairly well identified. This, which he says is 

 found in rivers,! seems to be Thelphusa fluviatilis, com 

 mon in southern Europe. 



There are other crustaceans which Aristotle calls 

 Karides, under which he includes three kinds, Kyphe, 

 Krangon, and a small kind of Karis, which never grow 

 larger. The Krangon, which is said to have all its feet 

 directed outwards, but its chelae turned inwards,!! may be a 

 Squilla or mantis shrimp. 



Many of the appendages of Squilla are short and not 

 seen in dorsal view; Aristotle says, apparently influenced 

 by this, that a large part of the body of the Krangon is 

 without feet. IT The information given about the two other 

 kinds of Karis is not enough to identify them, but Kyphe 

 has been thought to be the common shrimp (Crangon 

 vulgaris) . 



It is evident from Chapter xv. that Aristotle treated his 

 Malakia as if they had no connection with the molluscs. 

 He considered them to be the highest representatives of his 

 Anaima, mainly because of their sexual mode of reproduc 

 tion, their well-developed sense organs, and their arrange 

 ment of soft and hard parts, the former external and the 

 latter internal, as in his Enaima.** He distinguishes 

 the decapods from the octopods. He shows that the 

 former have eight short feet, each with a double row of 

 suckers, and also two long proboscis-like parts with suckers 

 at their ends, a large or long body, and a hard internal 

 support.lt 



Aristotle describes three decapods, viz., Sepia, Teuthos, 

 and Teuthis. The Sepia, according to him, is rather broad 

 and has a cuttle-bone, a narrow fin extending along the 

 whole body, and a large ink-bag situated as far as possible 

 from the mouth. 1 J He says that its eggs, like large, black 

 seeds, are connected together like a bunch of fruit. Both
