122 Mr. R. I. Pocock on the 



on board, it is not difficult to understand why the species 

 collected from time to time inland of the different ports that 

 were touched at, were for the most part considered by those 

 into whose hands they ultimately fell to be, if of interest at 

 all, certainly not worthy of special reports. However justi- 

 fiable this opinion was touching the majority of the land- 

 forms of life, it can scarcely be said to hold good when we 

 take the Myriopoda into consideration. Nor is this a sur- 

 prising fact, seeing that many of the localities visited were 

 isolated islands or localities rarely, if ever, explored by 

 collectors ; and consequently a large percentage of new forms 

 was obtained — large, that is, considering that those who 

 discovered them were without experience of the group, and 

 merely picked up such s])ecimens as presented themselves 

 during the search after land-forms in general. But, apart 

 from the new species, of which the value can only be appre- 

 ciated by a specialist, the interest of the collection touching 

 geographical distribution is in some respects very great. 

 This is notably the case with regard to Bermuda. 



Prior to the small report published by Mr. Bollman upon 

 the Myriopoda obtained by Dr. Angelo Heilprin in Bermuda, 

 I am not aware that any species of the group — authentically 

 named or otherwise — have been recorded from this island. 



Mr. Bollman mentioned five species in his paper; in the 

 ' Challenger' collection there are in all seven, five of them 

 being new to the locality and two of them doubtfully new to 

 science. 



The following is a complete list of the known species, with 

 notes respecting their extra-Bermudan distribution : — 



1. Scutigera coleoptrata (Linn.). 



Common in South and West Europe, Madeira, and Azores, 

 and probably introduced into Bermuda from the east. Not 

 Antillean j but possibly Nearctic, if Sc. forceps is the same 

 species. 



2. Lithohius provocator^ Pocock. 



Certainly closely allied to, if indeed it be truly distinct 

 from, the common European and N. -American L. forjlcatus. 

 Not Antillean. 



3. Liihohius bermudensi's, Pocock. 



Also a doubtful species. No doubt of European or Nearctic 

 origin. Almost certainly not Antillean, the genus Lithohius 

 being unknown in the West Indies.
