TWO NEW SPECIES OF ONYCHOPHOEA. 477 



to me. On the following day the same man found an addi- 

 tional specimen in the very tree in which he had discovered 

 the other five on the previous day. On the same morning 

 another Malay servant came across five more specimens in 

 another fallen tree, which was almost completely dry and 

 rotten. On the day in question I myself was with the men 

 who discovered the specimens, and am able to testify as to 

 the nature of the places in which they were found. The 

 kind of place which they seem to prefer for hiding during 

 the daytime is the interior of diy rotten wood. 



Preservation. — Of the thirteen specimens obtained five 

 were preserved in a mixture composed of ninety-two volumes 

 of saturated solution of corrosive sublimate in w^ater, and 

 eight volumes of glacial acetic acid ; three specimens in abso- 

 lute alcohol; four specimens in Flemming's weak solution; 

 and one specimen in four to five per cent, formaline, that is, in 

 a mixture of one volume of the commercial formaldehyde with 

 seven of water. All the specimens save the one preserved in 

 formaline were cut by a longitudinal incision, either doisally or 

 dorso-laterally, so as to preserve the internal organs. Unfor- 

 tunately, however, it happened — as if by the irony of fate — 

 that only male specimens were preserved in Flemming's solu- 

 tion, all the female specimens having been preserved either 

 in absolute alcohol or in the corrosive and acetic mixture. 

 This was a great misfortune, for the material preserved in 

 Flemming's fluid was almost perfect, while that treated with 

 the other solutions was far from reaching the same standard 

 of excellency. 



II. The Classification of the Onychophora. 



Before I proceed to describe the species here considered, 

 it seems necessary to give a historical account of the views 

 which have been put forward of the classification of the 

 Onychophora. 



Mr. Sedgwick, as was mentioned above, pointed out that 

 the Onychophora fell into three groups, namely, the
