44 Mr. Broderip’s Description of two 
That Lamarck’s Scut. longipes and coleoptrata and Latreille’s Scut. 
araneoides are the same, is evident from the correspondence of their sy- 
nonyms. Liatreille himself considers his Scut. araneoides and Linnzeus’s 
Scol. coleoptrata as identical, and adopts araneoides, “le nom spécifique 
«« de Linneus rentrant dans celui du genre ;’’ and a comparison of the 
different descriptions with the figures, cannot fail to shew that ours is the 
Scut. araneoides, 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 araneoides ; 
and as Lamarck says of his longicornis, “est elle vraiment distincte de 
«* la précédente ?’’ (the longipes/ it may perhaps turn out, after all, that 
there is only one well-known and established species of Scutigera, namely, 
the Scolopendra coleoptrata of Linnzus.

P.S. Iam 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. 6. 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.
