opsis. Sauripteris is of extreme interest from having the pectoral 
fin more closely resembling the tetrapod limb than in any other known 
form, as will be seen by the figure given. The jaw will be seen to 
agree very closely with that of the Stegocephalian. The Angular is 
large and situated as in Trimerorachis, except that it is almost entirely 
on the outer side of the jaw. The Surangular is larger than in 
Trimerorachis and forms the whole outer wall of the supra-meckelian 
fossa. The Articular is very much larger than in the Stegocephalians. 
It is badly preserved in the specimen, but its size can be pretty 
clearly made out. The Prearticular is as in Trimerorachis a very 
large bone, forming the inner wall of the supra-meckelian fossa and 
extending well forward. The Coronoid is narrow and lies between 
the Dentary and the Prearticular. It is situated similarly to the 
Coronoid in Trimerorachis. Its anterior development is unknown. 
The outer side of the jaw in the allied Rhizodopsis shows three bones 
in front of the Angular which are usually called Infradentaries. The 
hindermost is evidently the Preangular and the most anterior the 
Splenial. The middle one is evidently lost from the Stegocephalian 
jaw as the Preangular later becomes lost in the reptile. The relations 
of all the bones of the jaw are strikingly like those of the Stego- 
cephalian.

Per C. Ciaccıo. 
In una nota pubblicata parecchi anni fa?), che a quanto pare 
non & venuta a conoscenza del KurLr, io comunicai i risultati di al- 
cune mie ricerche relative alle cosidette „gelbe Zellen“ di SCHMIDT, ri- 
sultati che brevemente riassumo: 
1) Scumipt descrisse tali elementi nell’uomo e nel cane; io li 
riscontrai in parecchi altri Mammiferi (cavia, gatto, bue, topo, ghiro, 
riccio) ed anche in altri Vertebrati.
