N0 . 2.] DESCRIPTION OF THE FOSSILS. 101 



considerably greater than the width of the guard. The section here varies 

 from a rounded quadrilateral to a rounded trapezoid (in figs. 20c, d, 21b, 

 special attention is to he paid to the inner rings of growth in fig. 20c). In 

 the alveolar part the section becomes more and more circular (fig. 18b); the 

 dorso-ventral axis here is at first only very small, afterwards scarcely greater 

 than the thickness of the guard, the flanks, moreover, here being no longer 

 flattened. 



The beginning of the alveole, and the apical line are very eccentric in 

 position, and very near the ventral side. The distance of the apical line 

 from the ventral side of the rostrum varies in the different specimens (figs. 

 18 a, 19, 20 c) from one fourth up to one third of the dorso-venlral axis. 



A fragment of a small rostrum (with eccentric radiation), from brownish 

 clay, probably also belongs to the above-mentioned species. It shows the 

 phragmacone in a good state of preservation, and even remains of the crushed 

 pro-ostracum (?) are visible. 



The figured pieces correspond in size with the greater number of the 

 specimens; larger ones are rare. 



Belemnites m. f. subextensus Nik. Panderi d'Orb. was found loose 

 on July 12th, 1896, near the margin of the glacier NW. of Elmwood in 

 numerous pieces weathered out of the rock. One fragment lies embedded in 

 grey, brownish-weathered clay (like Cadoceras Tchefkini d'Orb. sp. and Quen- 

 stedtoceras vertumnum Sintz.). 



Some specimens are in clay-sandstone (No. 7) found July 16th, 1896, 

 above Elmwood 550 ft. 



Newton records our species from Elmwood and from the "western end 

 of Cape Flora". 



Remarks. There is no doubt that the species here described agrees 

 with the Belemnites Panderi which Newton described from Cape Flora. 

 Newton bases his determination on- a comparison with belemnites from the 

 Russian Jura, which Professor Pawlow had determined as Bel. Panderi. 

 Professor Pawlow, to whom I had the opportunity of showing my materials, 

 told me that they might well be determined as B. Panderi d'Orb., the more 

 so as Russian geologists include under this name several species which are 

 to be separated. On comparing the present species, however, with the orig- 

 inal description and the figures which d'Orbigny has given of his Belemnites
