424 Miscellaneous. 



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

 terminable Selachian fish and an imperfectly-preserved Dipnoan are 

 not of much interest ; but the latter seems to indicate a wq'^ genus 

 and species, Goafordia truncata, characterized by its very small 

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

 Pahconiscid genus MiiriolepU'Mi more completely defined than vras 

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

 the so-called Thrissonotus Colei from the Lower Lias of Lvrae Regis. 

 A new species, Myriohins latiis, with larger scales than the type, is 

 also added. A new genus and species of ]'alar;oniscid<T, Apateohpia 

 austrctUs, is remarkable for the extreme tenuitj' of the squamation, 

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

 family of Catopterida^ is instituted for the reception of C'atopterus 

 and Dict)jopy(je, and placed near the Pala^oniscida; on account of the 

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

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

 Hawkesbury Beds, but of Dicf)jopi/r/e there are three new species, 

 JJ. symmetrica, I), ilhistrans, and J), robusta. Close to the Cato- 

 pterida3 is placed the family of Pelonorhynchid;e, in which the same 

 non-correspondence of the median fin-su])ports and dermal ravs is 

 conspicuous. Two new species of Beloiiorhi/)i(hus—B.f/i;/as and B. 

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

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

 are imperfect indications of two species, named S. aiistrulis and -S'. 

 tenuis, A new genus, intermediate between Stmionotus and Dapedins, 

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

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

 skeleton of the allied genius Cleithrohpis, of which an outline-resto- 

 ration is given. The Pholidophoridic are represented by a small 

 species of Fholidophorus, appropriately named P. gregarins ; while a 

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

 described as Peltoplenras (?) duhius. Genera of the LeptoJeins type 

 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" Sj^ecics? 



There is in the Britisii ^luseum collection an example of Asft rias 

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

 Lyme Ilegis ; it was presented to the Trustees in 1^56 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 (Syuop. Starf. 1866, p. 1), but as he did not always (cf. 

 Ann. & Mag. Nat. Hist. ISlrl, vi. ]). IT'.O 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.
