44 Mr. Broderip's Description of tiro 



That Lamarck's Scut, longipes and coleoptrata and Latreille's Scut, 

 aranedides are the same, is evident from the correspondence of their sy- 

 nonyms. Latreille himself considers his Scut, aranedides and Linnoeus's 

 Scol. coleoptrata as identical, and adopts aranedides, " le nom specitique 

 •' de Linnajus rentrant dans celui du genre;" and a comparison of the 

 different descriptions with the figures, cannot fail to shew that om's is the 

 Scut, aranedides, livida, and variegata of their respective authors. I 

 suspect, from its omission in the " Genera," that Latreille considers 

 the longicornis of his " Histoire," synonymous with the aranedides ; 

 and as Lamarck says of his longicornis, " est elle vraiment distincte de 

 " la precedente ?" (the longipes J it may perhaps turn out, after all, that 

 there is only one well-known and established species of Scutigera, namely? 

 the Scolopendra coleoptrata of Linnaeus.

P. S. I am indebted to a friend for the drawings, and I mention this 

 because, in addition to their being better than my own would have been, 

 he is not interested either in the branch of science to which they refer, 

 or the subject of discussion which they are intended to elucidate ; his 

 pencil is therefore more likely to have been unprejudiced. Fig. b. was 

 sketched from the same animal as Fig. a., but coloured from one which 

 had been long in spirits and afterwards exposed to the air for two or 

 three hours.
