106 NOTES ON THE AUSTRALIAN AMPHIPODA, 



In most of its characteristics this species shows evident relation- 

 ships with Microdeuteropus. In fact it is only the form and pro- 

 portions of the gnathopoda (figs. 1 and 2) that separate it from the 

 normal members of that genus, with which it is connected through 

 the European M. versiculatus, Spence Bate.

 IV., p. 273, pi. XI., figs. 2. 



This curious species, which is not uncommon on the Coasts of 

 New South Wales and Victoria, was placed by me originally with 

 the Gammaridse ; a further examination shows that its relations are 

 rather with the Podocerides, the last pair of pleopods (fig. 7.) 

 being short, with slightly hooked spines on the outer ramus, and a 

 very short inner ramus with a simple pointed spine, and the telson 

 (fig. 8), being a small undivided plate with a strong hook at 

 each of its postei-o-lateral angles. 



The superior antennte have small two-jointed appendages — a 

 feature which I overlooked in my first examination. The flagellum 

 of the inferior antennae has three distinct joints. The anterior 

 gnathopods (tig. 4) might be described as very imperfectly sub- 

 cheliform — the propus having a small lobe at the base of the 

 dactylus. 



The nearest ally of the genus seems to be Coropliium, and C. 

 Lendenfeldi of Chilton (Trans. N. Z. Inst.. Vol. XVI., p. 260, pi. 

 XXL, figs. 1, a. to e.) is probably this species. 



XVII. Harmonia crassipes.
