80 THE HISTOEY OF ANIMALS. [B. IT. 



a juice resembling the mytis, and, between the teeth, a 

 piece of flesh resembling a tongue ; from the mouth a short 

 oesophagus extends to a membranous stomach ; in the part 

 of this nearest the mouth are three teeth, two opposite and 

 one below. 



12. And from the side of the stomach there is a simple 

 intestine, which is of equal thickness throughout, reaching to 

 the anus. All these parts belong to the carabi, carides, and 

 carcini ; and, besides these, the carabi have a passage sus 

 pended from the breast and reaching to the anus ; in the 

 female this performs the office of. a uterus, in the male it 

 contains the spermatic fluid. This passage is in the cavity 

 of the flesh, so as to appear to be between portions of the 

 flesh, for the intestine is toward the curved part, but the 

 passage towards the cavity in the same way as in quadru 

 peds. In the male this part differs in nothing from the 

 female, for both are smooth and white, and contain an ochre- 

 ous fluid, and in both sexes it is appended to the breast. 



13. The ova and spirals occupy the same position in the 

 carides. The male is distinguished from the female by 

 having in the flesh upon the breast two distinct white bodies, 

 in colour and position like the tentacula of the sepia ; these 

 appendages are spiriform, like the mecon of the whelk ; 

 their origin is from the acetabula, which are placed under 

 the last feet. These contain a red sanguineous flesh, which 

 is smooth to the touch, and not like flesh. From the whelk- 

 like appendage there is another spiral fold, about as thick 

 as a thread, below which there are two sand-like bodies 

 appended to the intestine, containing a seminal fluid. 

 These are found in the male, but the female has ova of a 

 red colour ; these are joined to the abdomen, and on each 

 side of the intestine to the fleshy part of the body, enclosed 

 in a thin membrane. These are their internal and external 

 parts. 



CIIAPTEE III. 



1. IT happens that all the internal parts of sanguineous ani 

 mals have names, for all these have the internal viscera ; but 

 the same parts of exsanguineous animals have no names, but 

 both classes have in common the stomach, oesophagus, and 

 intestines. I have before spoken of the carcini, and theii
