On a Crocodilian Skull from Kimmeridge Bay, Dorset. 75 



isted ; that the difference in minute structure between SigiUaria 

 and Stigma ria involves no serious difficulty if the former be regarded 

 as allied to Cycadacese ; and, further, that we do not know how many 

 of the Stigmarice belong to SigiUaria proper, or Favidaria, or to 

 such forms as Clathraria and Leioderma, which may have been 

 more nearly allied to LejndopMoios ; that the fruit figured by Golden- 

 berg as that of SigiUaria is more probably that of Lepidophloios, or 

 may be a male catkin with pollen ; and that he has found Trigono- 

 carpa scattered around the trunks of Sigillarice, and on the surface of 

 the soil in which they grew. He agreed with Mr. Carruthers in 

 regarding Mr. Binney's SigiUaria vascularis as allied to Lepido- 

 dendron. 



Prof. Morris thought that Clathraria and Lepidophloios ought to 

 be discriminated from the Sigillarice, as being rather more nearly 

 allied with cycadaceous plants, especially the former. He pointed 

 out the manner in which certain vascular bundles communicating 

 between the centre of the stem of SigiUaria and allied genera and 

 their bark might be mistaken for medullary rays. 



3. " Note on some new Animal Remains from the Carboniferous 

 and Devonian of Canada." By Principal Dawson, F.R.S., F.G.S., 

 Montreal. 



The author described the characters presented by the lower jaw of 

 an Amphibian, of which a cast had occurred in the coarse sandstone 

 of the Coal-formation between Eagged Reef and the Joggins Coal- 

 mine. It measured 6 inches in length ; its surface was marked on the 

 lower and posterior part with a network of ridges enclosing rounded 

 depressions. The anterior part of the jaw had contained about 16 

 teeth, some of which remained in the matrix. These were stout, 

 conical, and blunt, with large pulp -cavities, and about 32 longi- 

 tudinal striae, corresponding to the same number of folds of dentine. 

 The author stated that this jaw resembled most closely those of 

 Baphetes and Dendrerpeton, but more especially the former. He 

 regarded it as distinct from Baphetes planiceps, and proposed for it 

 the name of B. minor. If distinct, this raises the number of species 

 of Amphibia from the Coal-measures of Nova Scotia to nine. 



The author also noticed some insect- remains found by him in 

 slabs containing Splienopliyllum. They were referred by Mr. Scudder 

 to the Blattarise. 



From the Devonian beds of Gaspe the author stated that he had 

 obtained a small species of Cephalaspis, the first yet detected in 

 America. "With it were spines of Machairacanthus and remains of 

 some other fishes. At Gaspe he had also obtained a new species of 

 Psilophyton, several trunks of Prototaxites, and a species of Gyclo- 

 stigma.
