78 ME. E. B. NEWTON ON FOSSILS FROM MADAGASCAE. [Feb. 1 89 5, 



wards alluded to) was judged to be of Lower Oolitic age. This new 

 species was named Steneosaurus Baroni. 



Subsequently, in the same year, M. Stanislas Meunier 1 determined 

 some Cretaceous oysters collected by M. Gautier at Mahamavo as 

 Ostrea frons [=0. pectinata], Ostrea santoniensis [ = 0. Deshayesi\ 

 both of Senonien age ; and Ostrea columba [should be OrypTicea vesi- 

 cularis], of Cenomanien age. These species were well illustrated by 

 figures of the natural size. 



M. Meunier refers in the same communication to the occurrence 

 of Inferior Oolitic lamellibranchs at Belalitra (west of Mojanga, 

 lat. 15° 40' S., long. 45° 20' E.), resembling Modiola; to the 

 finding of Jurassic specimens of somewhat different horizon at 

 Andranomena (lat. 14° 15' S., long. 45° 26' 10" E.) representing 

 Natica, Pinna, Astarte, and FJiynchonella ; and to the discovery of 

 Dinosaurian relics at a place called Motety. 



Finally, Mr. J. T. Last, 2 in a popular newspaper article, mentions 

 that he has collected in the northern part of Madagascar (at a spot 

 about 20 miles east of the Bay of Narrinda) the remains of a gigantic 

 Dinosaur, which are now located in the British Museum.

This species has been previously recorded 3 from the same 

 neighbourhood. 



Peeisphinctes, sp. (probably allied to poly gyratus, Eeinecke). 



This is a fragment of the body-whorl of a large specimen, in 

 which the sutural characters are not sufficiently exhibited for 

 specific determination. 



Laterally there are five distant and coarse primary ribs, from 

 each of which proceeds a kind of double bifurcation bearing four 

 finer ribs, and these pass over the dorsal part of the shell without 

 interruption. Involution occupies about one half of the surface of
