52 THE VOYAGE OF H.M.S. CHALLENGER. 



1782. Berkley, Lefrancq de. Le Francq van Berkhey (Cams. Bibl. Zool.). John 

 Le Franc van Berkley, born 1729, died 1812 (Maunders). 



Johaun Franz van Berkliey's Naturgeschiclite von Holland, aus dem HoUiind- 

 ischen iibersetzt," has the first volume dated Leipzig, 1779, the second, Leipzig, 

 1782. This German translation of the work is the only one I have been able to 

 obtain, and in the second volume the translator gives notice that he has taken the 

 liberty of considerably curtailing the original. Li point of fact, all the zoology 

 seems to be omitted. From local notices in the work it may be inferred that the 

 author's name was certainly van Berkhey. 



" He published in Dutch a history of Holland, geographical, physical, natural, and civil, of which 

 a French translation appeared in 1782. He was the first to change the Linnean classification 

 of the Crustacea, forming them into a separate class, which he placed immediately before that 

 of the Insoota. But besides that he only characterised his divisions in a complicated, vague, 

 and often unmeaning way, he departs from the natural order, by placing the Testacea below 

 tlie insects, so that the Crustacea eome next to the bony fishes." Latreille, Consid. gen., 

 pp. 18, 19, ISlOi Compare note on Brisson, 1756, in regard to the question of priority, 

 since in regard to arrangement the classifications by Brisson and Berkhey seem to have been 

 practically the same.

Among the Apterous Insects he gives, on page 107, " 243, Cancer pulex (Faun. Svec. 2041). 

 Marflo," which, he says, is not only in very great numbers on the strand, but also out in 

 deeper water, where it does great damage, as well to the nets as to what is caught in them. 

 He thinks that it would be difficult to get a sufficient supply of horse-hair for making the 

 under part of the nets, which was the preventive believed in against these depredators. 



For "244, Cancer medusarum," he refers to "Str0m's S0ndm. Beskr. 188, Tab. 1, fig. 12, 13," 

 and considers that the description and figures given by Str0m are very accurate, he himself 

 having had the opportunity of comparing them with specimens taken from Medusa aurita. 



246 is given as " Cancer macrourus articularis manibus adactylis femoribus posticis orbicularibus 

 spinis caudae bifidis (Act. Soc. Sc. Hafn. 9, D. 588, Tab. viii.), Ogn, Aat." It is like a 

 little Marflue, but nearly white, with red eyes, and is much fatter, though smaller than the 

 Jlarflue. Another species, like it, but much larger, is called by the inhabitants, Gr0nlands- 

 Ogn, the presence of which indicated the speedy arrival of fish and whales. 247 is "Cancer 

 filiformis (Syst. Nat. 1056), SqviUa lohata (Miill. Prodr. Zool. Dan. 2359)." 



The Latin description of 246 relates to Str0m's Orchestia, 1765, whereas Mohr's own account of 

 it probably refers to some species of Anomjx, at any rate not to an Orchestia. 247 is 

 identified by Boeck with Caprella sejjienhionalis, Kr0yeT, but for this identification there 

 seems to be no adequate ground. Mohr's own references have to do with Caprella linearis.
