XLVIIl] PITYOSTROBTTS 393 



same locality is named by Gardner Pinus Bailyi^. These Irish 

 specimens agree in the cones and foliage-spurs with such recent 

 species as Pinus halepensis and P. Pinaster, but the apparently 

 erect position of the cones of the fossil type is a distinctive feature. 

 Tertiary cones similar to Pityostrohus Plutonis are illustrated 

 by Pinus robustifolia Sap.^ from Provence, P. Kotschyeana (Ung.), 

 originally described by Unger and recorded by Tuzson^ from 

 Hungary, P. transsylvanica Pax*, a North American form, which 

 the author of the species compares with Pinus Balfouriana, and 

 ,P. prae-montana described by Mogan* from Lower Austria. 



Pityostrohus (Pinites) palaeostrohus (Ettingshausen). 



This type originally described by Ettingshausen* from Haring 

 in the Tyrol is recorded from many Tertiary localities. The cones 

 are ovate sub-cylindrical with scales of the Pinus Strobus form and 

 the needles are borne in fascicles of five. Heer'' refers to this species 

 some thin and long needles from the Miocene of Greenland, but it is 

 not clear that the needles are in fives. The species is recorded from 

 Hungary^, Germany, France, and elsewhere. A cone of similar 

 form is described by Unger* from the Ohgocene of Kumi as Pinus 

 megalofis and it is associated with quinary fascicles. 



Pityostrohus MacClurii (Heer). 



This species described by Heeri" as Pinus (Abies) MacClurii 

 from Miocene beds in Banks Land, lat. 74° 27' N. is represented by 

 a specimen in the Dublin Museum. The narrow oval cone, 6x1-5 

 cm., consists of imbricate scales with the upper margin rounded or 

 irregularly truncate: some of the scales show indications of a pair 

 of seeds. Though similar to cones of Picea, the fossil cannot be 

 definitely assigned to any recent genus. Similarly, Miocene speci- 

 mens of cones, scales, and leaves from Spitzbergen referred by 

 Heer^i to Pinus Ahies L. do not afford satisfactory evidence of 

 their generic position.
