the investigation, and is illustrated by ten quarto plates. An inde- 

 terminable Selachian fish and an imperfectl\^-prescrved Dipnoan are 

 not of much interest ; hut the latter seems to indicate a new genus 

 and species, Gosfordia truncata, characterized by its very small 

 head, laterally compressed body, and minute striated scales. The 

 Pala3oniscid genus 3If/riolepis is more completely defined than was 

 possible in the original description ; and the fish is compared with 

 the so-called Tlwissonotus CoJei from the Lower Lias of Lyme Regis. 

 A new species, Myriolepis latus, with larger scales than the type, is 

 also added. A new genus and species of Palaeoniscidap, Apateolepis 

 austrcdis, is remarkable for the extreme tenuity of the squamation, 

 which is usually destroyed, except on the upper caudal lobe. The 

 family of Catopteridae is instituted for the reception of Catopterus 

 and Dictyopyge, and placed near the Palaeoniscidae on account of the 

 fact that the endoskeletal supports of the median fins are fewer in 

 number than the apposed rays. Catopterus is not known in the 

 Hawkesbury Beds, but of Dictyopyge there are three new species, 

 I), symmetrica, I), ilhistrans, and I), rohusta. Close to the Cato- 

 ptei'idae is placed the family of Belonorhynchida), in which the same 

 non-correspondence of the median fin-supports and dermal ravs is 

 conspicuous. Two new species of Belonorhijnchas — B. yiyas and B. 

 gracilis — are described at length, and add much to previous know- 

 ledge of the genus. Of the typically Triassic fish, Semionotus, there 

 are imperfect indications of two species, named S. austraJis and S. 

 tenuis. A new genus, intermediate between Semionotus and Dapedius, 

 is termed Fristisomus, having the three species P. gracilis, latus, and 

 crassus, and much new information is added concerning the exo- 

 skelcton of the allied genus CJeithrolepis, of which an outline-resto- 

 ration is given. The Pholidophorida3 are represented by a small 

 species of Pholidophorus, appropriately named P. gregarius ; while a 

 small, short, and stout fish with three series of deep flank-scales is 

 described as Peltopleurus (?) dahius. Genera of the Leptolepis tj'pe 

 are entirely wanting ; and, as a whole, the fauna under considera- 

 tion seems to be most nearly paralleled by that of the Keuper of 

 Europe. 



Is Asterias tenuispinis, Lamlc, a "■British'" /Species? 



There is in the British Museum collection an example of Asterias 

 tenuispinis, Lamk., which is, with a query, stated to have come from 

 Lyme E,egis ; it was presented to the Trustees in 1856 by the late 

 Lord Enniskillen. The only writer who, to my knowledge, has 

 reported the English coast as one of the habitats of this species is 

 Dr. Gray (Hynop. Starf. 1866, p. 1), but as he did not always (of. 

 Ann. & Mag. Nat. Hist. 1841, vi. p. 179) distinguish between this 

 species and A. glacialis, which is undoubtedly British, his evidence 

 is not unimpeachable. Can any naturalist acquainted with the 

 British fauna tell me that he has found this species on our shores ? 

 From its known area of distribution one might well have done so.
