 with little transparent bodies in form like imil>ivll:is. of which 

 the disks are rayed these are tin- rejected skins. 



The slow movements of the Ponlpe a re very st ran^e : it ele- 

 vnles it> lody and walks aloim" on the recurved points of iu 

 arms, and without the assistance of its siphon. But in a lar^e 

 Itasin the roiilpc swims i-eadily and without t he a wkwardnc 

 which I before remarked of its movements in an aquarium. Its 

 rapid swimming is always retrograde; its body and arms main- 

 tain a hori/ontal position, the latter remaining absolutely passive ; 

 the siphon alone bcin^ used. 



When the Ponlpe swims, its color is a little ditferent from that 

 which it possesses when in repose, and I have frequently re- 

 marked a colored longitudinal ray stall inu' from behind the eyes. 



I have been a witness only once to the forward swimming of a 

 Ponlpe: it progressed very slowly, in truth. The arms, divided 

 into two symmetrical bundles, were turned back on the body. 

 This position is very unfavorable to swimming; the resistance of 

 the water is much greater, and one can readily comprehend that 

 the animal would use it rarely. 



The number of respirations is variable, but much inferior to 

 that of the Sepias: it averai:v> from thirty to fifty in a minute. 

 It i> probable that in thcM-athc Poiilpe respires much more 

 slowly. In the aquarium respiration is accelerated by the vitia- 

 1 ion of the water.*
