ONCHIDIIDiE. 
Onchidium celticum (Cuv.). The organ opening near the hinder end on 
the under side of the mantle, regarded as lungs by Cuvier, is really the 
renal organ, homologous to the organ of Boj anus in the Bivalves; the 
heart is situated according to the typo of the Opisthohranchia, and the 
respiratory function is performed by the dorsal surface of the mantle 
and its appendages, according to the anatomical researches of J. Joyeux- 
Laffaie, C. R. xci. pp. 997-1000 ; abstract in J. R. Micr. Soc. (2) i. 
p. 229. [In consequence of this statement, this species, and possibly all 
Onchidiidee, must be removed from the Pulmonata to the Nudihranchia. 
—Reg.] 
I C. Semper regards (as usually) this organ as the lungs, and states the 
existence of a deeply-imbedded vas deferens, connecting the duct of the 
hermaphrodital gland with the penis, giving a table of 22 species exa- 
mined by himself, according to the presence or absence of an appendicular 
gland of the penis, of a cartilaginous tube in the latter or a cartilagi- 
nous papilla on it, and of distinct notches in the edge of the mantle ;
