157, pi. 5, 6. The author comes to the conclusion that the 
Pycnogonida are neither Arachnida nor Crustacea, that they are 
not allied to the Arachnida, and that they have, in common with 
the Crustacea, a NaujjliusAWG first stage of development, but that 
the further progress of their development is different from that of 
the Crustacea.
