Mr. G. Newport un new species of Myriapoda. 263 



Parmelia Fahlunensis. Not unfrequent on Glyder, but in fruit only 

 on Cader Idris. 



encausta. Glyder. 



sinuosa. Rather plentiful on a wall behind a small inn at 



the foot of Snowdon, between Carnarvon and Beddgelert. 



incurva. Not uncommon upon the walls about the foot of 



Snowdon. 



CoUema fasciculare. Below Aber waterfall near Bangor. 

 muscicola. In fruit at Cwm Idwal (in company with Mr. 



Borrer) and at Machynlleth. 

 Peliidea aphthosa. In fruit on the Brecon Beacon in South Wales. 

 Nephroma parilis (resvpinata, ft papyracea). More abundant than re- 



siipinata on a wall by the road one mile from Dolgelley to Bala. 

 Cetraria sepincola. On the largest of the stones called the Giant's 



Pebbles by a small pool on the road from Dolgelley to Tal-y-llyn. 

 Cornicularia bicolor. Ditto. 



XXXIV. — A List of the species 0/ INIyriapoda^ Order Chilognatha^ 

 contained in the Cabinets of the British Museum, with descrip- 

 tions of a new Genus and thirty-two new Sjjecies. By George 

 Newport, F.R.C.S., Pres. Ent. See. &c. 



This list of Myriapoda completes the enumeration and descrip- 

 tion of species in the cabinets of tlie British Museum, and in- 

 cludes the whole of the vegetable feeders, as my former list did 

 the carnivorous and mixed feeders. 



The Chilognatha have usually been regarded by naturalists as 

 the first order of Myriapoda, partly in consequence of the more 

 compact form of the head, and its similarity to that of the lai-va 

 state of hexapod insects, and partly from the general form of their 

 bodies being similar to that of those larvse. This was the view 

 taken of these animals by Latreille, Leach, Gervais, and some 

 others, and veiy recently even by Lucas. But a different, and, 

 as I believe, more correct iiew and arrangement have been fol- 

 lowed by Professor Brandt, who regards the Chilopoda as the first, 

 and the Chilognatha as the second division of the class. Although 

 I cannot entirely agree with Brandt in his division of the Chilo- 

 gnatha into masticating and sucking species, because, as Lucas 

 has recently remarked, there are species, even among the Chilo- 

 poda, which have the external organs of nutrition fitted only for 

 taking liquid food, as in the little Scolopendrella, 1 fully agree 

 with him in the superiority of the Chilopjoda, as an order, over 

 the Chilognatha, notwithstanding the less compact structure of 

 the head in the former. The general characters of the Chilopoda 

 certainly point them out as the most perfect animals of this oscu- 

 lant class of Articulata. The more compact form of body, the 

 reduced number of the organs of locomotion, the greater activity.
