0. longmani is the first species of this genus to be described from an 

 Australian reptile. Type specimens have been deposited in the collection of the 

 Queensland National Museum. 



Beddard's Ophidotcenia (1913(/, p. 85; 1913r, 

 p. 259) is a synonym of La Rue's Ophiotcenia 

 (1913, 1914). Dr. Beddard lays stress upon the 

 presence of uterine pores ventrally. La Rue 

 (1913, p. 481), however, has mentioned that these 

 may or may not be present in species of 

 Ophiotcenia, and he has figured such openings in 

 his 0. grandis (1914, pi. 9, fig. 101). 



If the possession of uterine pores be regarded 

 as liaving generie importance then La Rue 's genus 

 might be divided, his name being retained for 

 species in which the ventral outgrowths of the 

 uterus do not reach the surface whilst forms like 

 0. grandis Avould be transferred to Beddard's 

 Ophidotcenia. It seem advisable to retain both 

 groups of species under La Rue's Ophiotfenia* 



CCENURUS SERIALIS. Gerv. 



This larval parasite was taken by me in 

 October, 1910, from a Co.ypu rat, Mtjopotamns 

 cog pus, which had died in the Sydney Zoological 

 Gardens. The specimens were found in the 

 musculature adjacent to the ribs. C. scrialis, or 

 better Muliiceps scrialis, has already been reported 

 on a few occasions from this host {sec Hall, 1910, 

 p. 61) in America. It is not uncommonly met 

 with in rabbits in Victoria (Sweet, 1909, p. 507) 

 and New South Wales (Johnston, 1910, p. 343), 

 where it sometimes occasions serious injury. In 

 one instance, a rabbit was found by Dr. Cleland 

 and myself, whose left eye had been completely 

 destroyed by the development of a large cyst of 

 this parasite in the connective tissue in the socket 

 of the eye, the organ having become compressed 

 and greatly flattened between the cyst and the 

 orbit.

NEMATOTffiNIA, sp. 



A few tiny cestodes collected by Dr. S. J. Johnston, of Sydney University, 

 from New South Wales frogs, have been determined as belonging to this genus. 

 They resemble N. dispar in general anatomy (Luhe, 1910, p. 124), but are quite 

 small, the largest measuring 6 to 7 mm. in length and about -2 mm. in maximum 

 width. 



The species was taken from the duodenum of one specimen of Hyla 

 freycineti and from the intestine of two Ilypcroleia m.armorata, while fragments 



* Beddard {I9l3b, p. 157) has figured rudimentary uterine por.^s in Ichthyotcenia gabonica 

 Bedd. ( = Ophiotcenia rjahonica) and (1913c, p. 255) in Solenotcenia viperis Bedd.
