(1893cf, p. 258). My specimens were forwarded from 



Ipswich. Immature forms have been fouund by me in 



the liver. 



Agchylostoma caninum: Ercol. 



Found locally in dogs and cats. Its presence in dogs 

 in Brisbane (presumably), is inferred from a statement 

 by Dr. Bancroft (1901, p. 41), while I have recorded its 

 occurrence in the dog in X.S. Wales and Victoria. As 

 far as I am aware, this hook-worm is now recorded for the 

 first time as parasitising cats in this continent. 



Gigantorhynchus moniliformis, Bremser. 



Occurs in Mus decumanus and M. alexandrinus in 

 Brisbane, but apparently hitherto unrecorded. 



Echinorhynchus menurce, n. sp. 



(PL IV ; Figs. 39, 40). 



A single specimen, 19 mm. in length and i'lmm. 

 in breadth was taken from the intestine of a lyre-bird, 

 Menura superba. near Gosford, X.8. Wales. Owing, to 

 the large number of eggs overlying the female organs, 

 very little of the internal anatomy was recognisable. 



The parasite has a maggot-like appearance, being 

 somewhat narrower at the anterior end. The body wall 

 is thin and delicate and consequently readily distorted. 

 The small tubular rostellum (Fig. 39) measures about -16 

 mm. in diameter, and bears about seven whorls of very 

 numerous, narrow, sharp- pointed hooks, each of which 

 projects about -04 mm. beyond the surrounding collar. 

 The proboscis sheath is relatively long. 



The only part of the female genitalia recognisable is 

 the lower portion of the uterus, or perhaps more correctly, 

 the vagina, which terminates at the gonopore, the latter 

 lying at the base of a concavity. The elliptical eggs measure 

 •10 by -031 mm., and the embryos -068 by -019 mm. 



Echinorhynchus rotundocapitatus, n. sp. 



(PL IV ; Fig. 41). 

 This species occurs commonly (Johnston. P.L.S., 

 N.S.W., 1909, p. 590 ; P.R.S., Q'land, 1911, p. 238), in the 

 rectum of the black snake, Pseudechis porphyriacus , Shaw, 

 in various parts of New South Wales and Victoria.
