Hundreds of specimens, from Santa Catliarina and Parana, 

 liave lately passed tliroufi;li my hands, and show beyond doubt 

 that P. Kroyeri^ K. & L., is only a variety of the S]:)ecies 

 named Ixhinoderma signifera by Girard and Liuperus biligo- 

 tiigerus by Cope, hiome specimens are smootii, others are 

 covered with warts, others have the longitudinal folds charac- 

 teristic of P. iu-o^en; some have the snout rounded, others 

 have it pointed ; some are uniformly coloured on the back, 

 others are marked with insuliform spots, whilst others, again, 

 are striped. But all these differences are completely bridged 

 over when a large series, from the same locality, are examined. 

 The inguinal spots, which are rarely absent, are constantly 

 small and uncovered by the folded limbs. The metatarsal 

 tubercles are larger and more compressed than in P. gracilis^ 

 and the tibio-tarsal articulation does not reach beyond the 

 posterior border of the orbit.
