the great Cretaceous sea that covered so much of what is now the 

 central portion of the continent on the one side and the Pacific on 

 the other. 



Ten plates accompany the descriptions of the species ; and a table 

 is given of their ranges in the different subdivisions of the Vancoxiver 

 and Californian Cretaceous rocks. 



MISCELLANEOUS. 



On Hyale Luhhockiana (=Allorchestes imbricatus, Sp. Bate, and 

 Nicea Lubbockiana, Sjp. Bate), liy the Eev. T. R. R. Stebbing. 



At Banff this August I had the pleasure of being shown over the 

 museum of the place by Mr. Edward, the well-known naturalist. 

 In his collection of Crustacea I observed Allorchestes imbricatus, a 

 species of wbich I had long been in search. Upon examining the 

 rocks along the coast I found it living in great abundance. It was 

 easy to distinguish it from Allorchestes Nilssonii by the imbrication. 

 On closer view a large hooked and serrated spine on the hand in 

 the pereiopoda proved to be an equally constant and distinguishing 

 character. A spine, however, of this description is the special 

 characteristic of IS'icea Luhhockiana; and upon comparing the ac- 

 counts given by Mr. Spence Bate of Allorchestes imbricatus and 

 Sicca Lxhbocliana, I think it is evident that the two names belong 

 to one and the same species. As explained in the ' Annals ' for 

 May 1870, the generic name should be Hyale. Of the two specific 

 names, Luhhockiana will have the precedence. 



The difference in the length of the inferior antennae in the two 

 descriptions merely results from a difference in the age of the 

 specimens described. The question of the telson has already been 

 discussed in the paper above mentioned. 



On Robert Kerr's Translation of the ' Systema Natural ' of Linnaeus. 

 By Oldfield Thomas, Assistant in the Zoological Department, 

 British Museum. 



Having seen the above work quoted in certain of the papers on 

 North-American Mammalia by Dr. Elliott Coues, the quotations being 

 generally put in inverted commas, as though the work had not itself 

 been referred to, I thought it worth while to examine the cataloguo 

 of the Banksian Library, where, as 1 expected, I found a copy of 

 this rare and little-known book. It is dated 1792, and purports to 

 be a revised edition of Gmelin's 'Systema Nahme.' There are a 

 considerable number of species named in it, with full descriptions 

 and references. It was never continued beyond the first volume, 

 which contains the Mammalia and part of the Birds. 



Among the birds, nearly all the species additional to Gmelin 

 appear to be quoted from Latham's ' Index Ornithologicus ;' but 

 among the Mammalia, the new species described in Pennant's ' His-
