ON THE OVTPAROFS SPKCIES OF OiNYOHOPHORA. 407 



Sanger^s possession), the fact perhaps not being considered 

 worth noticing in the summary which Sanger gives, and which 

 (quoted by Leuckart) has been generally accepted as bearing 

 the ordinary interpretation. This summary (according to 

 the translation obtained in London by Professor Spencer) 

 runs as follows: — "Fifteen pairs of legs; sexual organs 

 between the last pair; the ' sole ' consists of three segments, 

 one long and curved, and two short and straight. New 

 Holland, Australia." In any case Sanger's statement as to 

 the number of legs appears to be completely neutralised by 

 Leuckart's. As to the argument derived from Sangei^'s 

 comparison of his specimen with P. brevis, it seems probable 

 that Sanger knew very little about P. brevis, for, as Mr. 

 Fletcher shows, he erroneously attributes the description 

 thereof to Blanchard instead of to De Blainville. Moreover 

 against this comparison we may surely set Leuckart's 

 comparison of P. novce-zealandige, Hutton. Leuckart 

 says (as quoted by Fletcher, Button's Abhandlung 'On 

 Peripatus novoB-zealandiae,' 'Ann. Mag. Nat. Hist.' [4], 

 xviii, Nov., 1876, pp. 361 — 369, pi. xvii) ''macht uns mit 

 einer Form bekannt, die 15 Beinpaare besitzt, wie der von 

 Sanger (J. B., 1870, S. 410) beschriebene P. Leuckartii, der 

 unserm Verf. freilich unbekannt geblieben ist, obwohl seine 

 neue Art vielleicht daniit zusammenfallt. Jedenfalls ist nicht 

 der P. novae-zealandiae, sondern der P. Leuckartii die 

 erste Art des Gren. Peripatus, die aus Australien kommt." 

 Surely if Leuckart, the owner of the specimen, thought it 

 was so similar to P. novas-zealandiaB with fifteen pairs of 

 legs that it might be identical, it is hardly likely that it after 

 all had only fourteen pairs. There can hardly have been any 

 misunderstanding of Hutton's original description, for Hutton 

 says " fifteen pairs of ambulatory legs, and a pair of oral 

 papillae." 



(2) The locality of Sanger's specimen, "found in New 

 Holland, north-west from Sydney," renders it extremely 

 improbable that it can have been 0. insignis, which is rare 

 even in the south, and has never yet been recorded from
