Remarh. P. pectimfer Can. measures from 700 to 800 ^. — 

 G. and. R. Canestrini, describing P. pectinifer Can, in AU. Heal 

 Istlt. Vetiet. Sc. Lett, ed Art. ser. 5, v. 7, p. 6, say: «Un nostio 

 esemplare gigante supera le misure esposte più sopia, perchè è 

 lungo min. 1,28 e largo mill. 0,80». Most problably this «giant» 

 was not a P. ])ectinïfer Can. but another species, e. g. my P. 

 enslfer. 



10. Liponyssus pipistrelli Oudms. 



Liponyssus muscull (C. L. Koch) deutonympha Oudms., in Tijdschr. 

 d. Ned. DierJc. Fereen., ser. 2, v. 8, p. 18, 19. PI. 1, fig. 1, 2. 

 31 October 1902. 



In the Tijdschrift der Nederlandsche Dierkundige Vereeniging, 

 ser. 2, V. 8, p. 17 and 18, I described a protonympha of Zi/jo;«mM* 

 as the deutonympha of Liponissus muscidl (C. L. Koch). This was 

 an ugly fault of mine, A deutonympha would have been provided 

 with a long peritrema; the creature described and delineated by 

 me (PI. I, fig. 1 and 2), however, has a very short peritrema, as 

 is only known in piotonymphae. Therefore it is a protonympha 

 of a hitlierto unknown species, for which I chose the name of 

 Liponyssus pipistrelli Oudms. 



It was caught by Mr, S. A. Poppe, on Vespertillo pipistrellus. 



11. On the larva of Spinturnix. 



In July 1902 my Notes, Fourth Series, issued from the press 

 (Tijdschr. d. Ned. Dierk. Vereen., ser, 2, v, 7). Here, p. 299, I 

 showed that an embryo, which I had dissected from the mother's 

 uterus, was provided with 8 legs, of which «legs 1, 2 and Shave 

 already their difìnitive position, i. e. quite close together, whilst 

 legs 4 are still remote a considerable distance; the legs 4 are 

 not so far developed as legs 1, 2 and 3, being still wrinkled. 

 This is a proof that the embryo passes through a larval stage 

 with 3 pairs of legs, after which stage it gets its npnphal pair
