Localities : — 



1. One specimen from the top of the Dandenong Ranges, 

 Victoria (A'ersAatu, ii. 72) (PI. XIX. fig. 29). Left chela enlarged, 

 right slender. 



2. One specimen, S. Gippsland, July 1891, exactly similar to 

 above. 



3. One specimen, Boxhill, near Melbourne, has right chela 

 enlarged, left slender. 



4. Two small specimens, Emerald, Victoria (E. Jarvis, viii. 04). 

 Left chela enlarged, right slender, the other with chelae subequal. 



5. Several (small) from Fern Tree Gully, Victoria. Some with 

 right chela enlarged, some with left. 



6. One specimen from Croydon, Victoria (F. P. Spry, 1. xi. 04). 

 Right chela enlarged. 



7. One specimen from Ringwood, Victoria {E. H. Hennell, 

 xi, 90). Left' chela enlarged. 



8. Several specimens, simply labelled " Victoria." Some with 

 right chela, some with left enlarged ; a few with chelae subequal 

 or equal. 



9. One very large specimen from the Launching Place, Victoria 

 {J. Coghill, 15. i. 07), with left chela enlarged. 



Remarks on the above two sj[)ecies, E. aifinis and victoriensis. 



These two species, which are veiy widely distributed in 

 Victoria, are clearly distinguishable from the Tasmanian E. fossor 

 by a number of characters, and from the succeeding species, 

 E. 2>hyllocerGus, by the remail<:able shape of the uropods in the 

 latter form. But the characters distinguishing E. affinis and 

 victoriensis are very slight, and it may be possible at some time 

 trO merge them together in one species, victoriensis. The only 

 really satisfactory cliaracter is the size of the last pleurobi-anch, 

 which is reduced in victoriensis and well developed in affinis. 

 The only other character which is of use in separating the two 

 forms is the shape of the enlarged chela, which is shorter and 

 broader in a^nis than in victoriensis ; but since the enlarged 

 chela is not always developed, this character is an unsatisfactory 

 one. 



Engjsus phyllocercus, sp. n. (Pis. XIX. &, XXL figs. 30, 31. 

 & 36.) 



All the pleurobranchs are of approximately equal size, the last 

 one not being reduced. 



The exopodite of the third maxillipede is reduced, but is 

 clearly to be seen, and it is tipped with sevei'al plumose hairs 

 (PI. XXI. fig. 36). 



The antennal scale ends in a spine which is less elongated than 

 in the preceding two species. 



The first antenna, is similar to that of preceding species. 



The great chela has both the upper and lower borders of the
