of difficulty. The larva is usually called P. dcuticitlatum, 

 Uml., though Liinjiuthihi so vm to, Frol. is an earlier name 

 and therefore the more correct one. The adult is also 

 variously named by the writers above referred to, the 

 more common names being L. taenioides, Rud., and L. 

 vhinaria, Pilger. Of these two names the latter is the 

 older, and therefore the better to use. However, the 

 specific name sn-rata was used for the larva by Frolich in 

 1789, whilst rhinavia was used in 1802 by Pilger, and 

 denticiOatum in 1805 by Rudolphi. The usual method in 

 mdminthology appears to be to retain the earliest name 

 :. ; 'l»li«-i I in the adult as the true specific name even though 

 the larva may have been named previously. This has led 

 to the name L. rhinavia, Pilger and /,. taenioides, Rud., 

 Iii-ing used in preference to the older L. sen-ata, Frolich. 

 Sainhon, however, accepts the last named as the true name 

 apparently following the " International Code " ; which is 

 now binding on helminthology as well as other branches 

 of zoology. 



The possible causal relationship of this parasite to the 

 endemic haematuria common in bovines in certain of our 

 coastal districts is a matter now under investigation by us. 

 This disease is characterised by the presence of small 

 angiomatous growths with telangiectases in the bladder of 

 infected animals. From time to time, extensive haemor- 

 rhages occur from the vascular tumours leading to haema- 

 turia and subsequent anaemia, etc. In the only two 

 animals thus affected examined by us for Pentastomes, 

 these were found. It will be necessary of course to ascertain 

 whether healthy cattle in the same district are also affected 

 and whether the parasites can be found in animals from 

 other parts of New South Wales. 2 The discovery of these 

 parasites in the cases referred to, suggests that they may 

 play a role of much economic importance, but it would be 

 premature to discuss the question further at present with 

 the limited material and facts at our disposal.
