The huvie of Salientiaiiave been (livided into two {ironps by liataste, 

 (he .Mediogyrini and tlie Laevogyrini.** In (he former (he external 

 branchial orifice is on the median line of tlie inferior surface; in the 

 otlier it is on (he left side. To the former division belong the Disco- 

 giossida'; (o (he latter all remaining Salienda, except Aglossa, wheie 

 there are two spiracida, one on each sid«' (Amphigyrini Heronlfoyer). 



In the stage which immediately follows (he separa(ion from the o\;{!; 

 the tadpoles of Salientia possess one or two pecidiar siu,.»lng disks on 

 the under side of the head behind the i)osition of (he moudi. Their 

 form differs (Plate 78) widely in dilferent g«'nera of Annra, and will 

 alford a valuable means of identifying the larvic. I n />/.vcf*///r».v.\».v pirtiis, 

 the adhesive organ behind (he moulh, is hemispherical, wi(h a V-shaped 

 groove on its surfatie, the V opening forward. In Prlohufca J'uscus the 

 adhesive organ is V-shaped, with a V-shajx'd giomt' on i(s surface, and 

 the limbs of the whole organ extending furwaid (o eiiilirace (he angles 

 of the mouth. In lUifo vnUjark the organ is V-shapt-d, wi(h a V shaped 

 groove, and the limbs of the V come into «'on(act wi(li (he angles of tlu^ 

 mouth. In Bufo riridis (he organ iNcrescentshaped, nut in contact wi(h 

 the mouth, but a li(tle behind i(, as in Dis'-cglossus, and wi(h a widely
