Remarks.—This species of Anoplodactylus, which I have called erectus 
on account of the position of the caudal segment, is in many respects 
very similar to A. fetiolatus (Kroyer). 
shown in the following table: 
A. petiolatus. 
Trunk ‘‘somewhat short and stout, 
and, relatively to its length, 
rather broad.” 
Lateral processes not much sepa- 
rated. 
Caudal segment long, cylindrical, 
abruptly acuminated, placed 
horizontally. 
Proboscis of plain cylindrical form, 
obtusely truncated. 
Immovable finger of chela almost 
quite straight. 
Ovigera nearly as long as animal. 
Legs hardly two times length of 
animal. 
Second tarsal joint strongly curved ; 
4 to 6 spines on proximal part 
of sole. 
The important differences are 
A, erectus, 
Trunk rather slender. 
Lateral processes well separated. 
Caudal segment not especially long, 
more or less conical, directed 
upward at a sharp angle. 
Proboscis not plain cylindrical, 
narrower in basal portion. 
Fingers of chela both curved. 
Ovigera as long as, or longer than, 
animal; third joint especially 
proportionately longer than in 
A. petiolatus. 
Legs proportionately longer; two 
and one half times length of ani- 
mal. 
Second tarsal joint not strongly 
curved; 7 to 11 spines on proxi- 
mal part of sole.
