NO- 2.] DESCRIPTION OF THE FOSSILS. 



51 



The state of preservation of some remains of belemnites and Pseudomo- 

 notis found on August 2nd, 30 feet above ttie sea level, is peculiar. They were 

 lynig free in the clay (in situ) together with stone-nodules of type 4. The 

 greatly broken pieces are covered with a crust of crystals of gypsum. 



Considering the state of preservation of the fossils m conjunction with 

 the petrographic chai-acter of the rocks, the Jurassic strata of Cape Flora give 

 the impression of deposits having been formed near the shore. In the rough 

 water near the shore, the hard parts of the animals were easily broken. The 

 pressure of the heavy masses above, and fractures in the rock, then accom- 

 plished what was still wanting to make the state of preservation of the animal- 

 remains embedded in clayey, marly and sandy masses, as bad as it could 

 possibly be. 



2. DESCRIPTION OF THE FOSSILS. 



EGHINODEBMA TA. 



CRINOIDEA. 



The Echinoderms are only represented by a single fragment of a crinoid 



stem, in the material collected by Prof. Nansen. This belongs to the genus 



PENTACRINUS, Miller s. str. 

 and was determined as: 



Pentacrinus sp. ex. aff. bajociensis (d'Orb.) P. de Loriol. 



PI. I. fig. 1. 



(Cf. 1886 Pentacrinus bajociensis d'Orb., P. de Loriol: Crinoides. Paleon- 



tologie frangaise. Terr. jur. vol. IX. p. 144, pi. 150, 151, figs. 1—4). 



The fragment of stem before me consists of 6 joints. The alternating 

 joints are somewhat different in shape and size. The larger and longer joints 

 are pentagonal in outline with rounded corners; they are not incurved in the 

 interpetalous regions, or only very slightly. The joints alternating with them 

 are a little smaller and shorter. Their contour is also rounded pentagonal, 

 but in the interpetalous regions they are shghtly incurved at obtuse con- 

 cave angles. The outer side of all the joints is inflated and arched, almost 

 carinated. The outer surface is thickly tuberculated. Near the sutures, 

 the tubercles are closer and finer than along the middle of the inflated side. 

 The tuberculating has to some extent become indistinct from weathering.
