Locality — Herberton, in forest country. Examples, three : 

 2 <?, 1 ? . The collector, Mr. Broadbent, notes of it that it has all 

 the habits of an Acanthiza, frequenting open places and preferring 

 small bushes. 



A. reguloides is the only species with which it can be con- 

 founded. It is, however, a larger bird with a shorter tarsus, and 

 is further distinguishable by the colour of the legs, and the 

 squamated appeal ance of the throat and parts about the head. 



ANATOMICAL NOTES ON THE HELICIDJE;

PART III.

Helix porteri, Cox ; of this species the jaw is orbicularly arched, 

 crossed by numerous fine ribs which denticulate both margins, ends 

 rounded. The centre cusp of the rachidian tooth is small, ovate, 

 acute, reaching half-way along the basal plate, bearing on both sides 

 a minute denticuie anterior to its cutting portion. The twenty 

 laterals ai e rather larger than the rachidian, and elongate as they 

 recede from it ; the small accessory distal cusp, possessed by each, 

 gradually becomes more defined as it reaches the more distant series, 

 a denticuie appears half-way up the proximal blade about the 

 fourteenth series. The character of the teeth abruptly changes in 

 the twenty- fourth series, where the inclined laterals are suddenly 

 replaced by the upright marginals. The latter numbering over 

 twenty, are much alike, consisting of a large; lanceolate cusp cleft 

 half-way down, and a small shtrp accessory distal cusp. 



Penis sac terminating in a flagellum, anterior portion pyriform, 

 insertion of the retractor muscle distant from entrance of the short 

 vas deferens. Genital bladder small, ovate, on a rather long wide 

 duct.
