 new G. of fish near to Achirus found in the Kiver Schuylkill ; it hss only three fins : dorsal, anal 

 and caudal. "Also the description and figure of a large and beautiful new catfish from the Eiver 



* " This name is very good, but if not agreeable to all, I have half a dozen others to offer as substi- 

 tutes : Biopores, or Zoopores, or Leptremes, or Adelostomes, &c. Because it is my wish that this class or 

 large section of animals should bear a good name given by me, instead of the delusory one of Animal- 

 cula or -microscopic anim^als, which does not apply to all. . . . The Miasmata or miasmic animal- 

 cula of the air, may be the invisible birds of this class, or aerial insects floating in the air." — (Raf. 

 op. cit., p. '.jl.)
