Myriapoda 189 



synonym of /. fallax but I think the two species are distinct. 

 There is a marked difference in the size of the auxiliary 

 copulatory organs in relation to the size of the animal, and the 

 form of the metamorphosed first pair of legs in the male differs 

 considerably in the two animals. In the specimens which 

 I have examined about 50 of J. longabo and 200 of /. albipes 

 there is a slight difference in the form of the anal spike. 



Carpenter records Julus luscus, Meinert, in Ireland. Ver- 

 hoeff describes a species of Julus which he calls J. britannicus 

 as occurring in England and resembling J. luscus very closely. 

 It seems to me not improbable that Carpenter's species was 

 really Verhoeff s J. britannicus as the two species resemble 

 one another so closely, and /. luscus has not, so far as I know, 

 been found in Great Britain. 



The Chilopoda have been divided by Pocock into Geophilo- 

 morpha, Scolopendromorpha, Craterostigmomorpha, Lithobio- 

 morpha and Scutigeromorpha. Of these, all except the Cra- 

 terostigmomorpha are represented in Britain. 



1. Of the Geophilomorpha there are the following 

 species: Geophilus longicornis, Leach; synonyms, G. elec- 

 tricus, Gervais ; Arthromalus longicornis, Newport; A.flavus, 

 Newport; A. similis, Newport. This species is found in 

 Austria and Germany, and varieties, or nearly allied species, 

 in Portugal and the Azores. I have found it fairly common 

 in Cambridgeshire. Arthromalus carpophagus, Newport; 

 synonyms, Geophilus condylogaster,~La,tzQ\; 6r. so^a/zs, Meinert; 

 found in England, Ireland, and Austria. Geophilus humili, 

 Newport ; I believe this to be synonymous with Scolioplanes 

 acuminatus. G. subterraneus, Newport ; I am unable to say 

 whether this is a distinct species. Scolioplanes acuminatus, 

 fairly common in Cambridgeshire, and England. It is also 

 found in Germany and Austria. Scolioplanes maritimus, 

 Leach. Verhoeff considers this as a race or a variety of Sc. 

 acuminatus or a variety of Sc. crassipes. G. breviceps, Newport, 

 synonymous with the above (Sc. crassipes).
