posterior gonopods (Fig. 3) are attached to a small but distinct 
sternum with unusually long tracheal apodemes; each is likewise 
proximally produced into a coxal apodeme (Cxap). The gonopod 
has the form of an elongate, flattened cylinder, distally narrowed, 
with a broadened setose lobe on the aboral side and a more slender 
anterior process; when seen in anterior aspect this latter structure 
appears to be basally articulated and may represent the telopodite 
remnant. 
II. Euethogonus Chamberlin 1920 
Bull. M. C. Z., 64: 166. Type species, E. hardyi Chamberlin, by original 
designation. 
This monotypic genus was diagnosed as differing from Amastigogo- 
nus (Brolemann, 1913) in having the first pair of male legs “nor- 
mal” in appearance, with a tarsal claw and the basal segment not 
enlarged. The “pseudoflagellum” of the anterior gonopods was also 
said to be slender and acicular instead of “ribbon-shaped” as in 
Amastigogonus. 
Dr. Levi sent the type material of E. hardyi for my examination. 
This revealed that, again, Chamberlin failed to look carefully at the 
specimen, in fact the head was still reflexed against the anterior legs 
and the latter could really not be seen clearly until head and collum 
had been displaced. Figure 6 shows what the first pair of legs looks 
like. They are essentially similar to those of Amastigogonus tasmani- 
anus as shown in Fig. 32 of Brolemann’s 1913 paper on myriapods 
of the Australian Museum. The same may be said for the gonopods 
themselves. It is true that the “pseudoflagellum” (perhaps soleno- 
merite would be a better term for the structure) is shorter than in 
A. tasmanianus , but in mesal aspect (Fig. 8) it could certainly be 
perceived as laminate and not needle-like. Since the type specimen of 
E. hardyi agrees so closely with Brolemann’s account of tasmanianus 
in virtually every detail, I see no reason to separate the two species 
generically. Euethogonus is herewith regarded as a junior subjective 
synonym of Amastigogonus which has seven years priority. It is 
quite incredible that Chamberlin did not really try to examine the 
first male legs of hardyi , considering how closely it matched Brole- 
mann’s species in all other respects.
