The material is from- the triassic Fish level and collected in the sumraer 

 of 1915 hy Ewk A-son Stensiô. A new species, Peltosiega Erici is described. 

 Only the large posterior part of the skull is preserved, and this is in the main 

 developed in the usual manner. Especially noteworthy is the existence of 

 a small foramen quadrati. In addition to the foramen jugulare there is ano- 

 ther foramen on the condylus, probahly the foramen condyloideum for the 

 exit of the nervns hypoglossns. The foramen pariétale is developped in a 

 différent way, than what is generally the case, inasmnch as it lies in an 

 impressed, not skulptured triangnlar area of the cranial roof. 



On a spécimen of the previously described species, Lyrocephalus Euri, 

 a probably cartilaginous ethmoidal région is preserved and is perforated 

 by the olfactory nerves. The interfrontale oecurring on the cranial roof 

 of several stegocephalians might be homologons to the mesethmoidenm of 

 the teleostom Fishes. The sphenoidenm is high and narrow. The epipterygoid 

 also is preserved on the spécimen and is joined to the cranial roof by a possibly 

 cartilaginous part. Behind the large trigeminus foramen lies the prooticum, 

 which is likewise preserved. Between this bone and the cranial roof there 

 is a bone, which is regarded as the sphenoticum.

 snout of this species was even more elongate than what was previously 

 known. Aulhor 's abstract.

The vertebra is a pectoral one with four nutrition foramens on the ventral 

 side. It is obtained from the Trentone séries.

In the fine-grained Mucronata Limestone at the Rabelof lake there has 

 been found an accumulation of well-rounded stones, which hardly could 

 be anything else than gastrolites of some Saurian. In connection with the 

 description of this find the author gives an account of the occurrence of 

 gastrolites in widely separated groups of living and extinct vertebrates and 

 calls attention to the différent facts which aught to be taken into consi- 

 dération when dealing with stones which might be regarded as gastrolites.
