ORECTOLOBID.E. 

 ORECTOLOBUS TENTACULATUS Peters.' 

 In my "Cheek-List of Queensland Selachians"- I expressed a doubt as to 

 whether the Port Adelaide and CajX' York sharks recorded by GiJnther- undei- 

 this name were identical, pointing out that the species had never been taken 

 at any intermediate station. This doubt was, however, dispelled by the reception 

 of a fine example forwarded from Port Darwin to this Museum by Mr. G. P. Hill. 



STEGOSTOMA TYGRINUM (Bonnateire).* 



During Christmas wei'k one of these sharks was captured at Southport, 

 and forwarded to the Queensland University. 



MOBULID.E. 



MORULA Rafinesque. 

 MOBULA EREGOODOO (Cantor).^ 



Through the kindness of Mr. J. Hirst Stevens, Inspector of Fisheries, 

 the Museum became possessed of two fine examples, a male and a female, of 

 this "horned ray," which had been exhibited in the Fisheries Court of the 1917 

 Agrictiltural Show. Since that time I know of a third specimen having been 

 caught in Moreton Bay, but this was unfortunately lost to science, its captors, 

 having brought it up the river as far as Pinkenba, deciding to jettison it. Though 

 from the infrequency of its capture the species is but little known to our 

 fishermen, whether pi'ofessional or amateui', it is possibly by no means so rare 

 as is generally supposed. 



ARGENTINID.3^. 

 RETROPINNA SEMONI (Weber). « 

 During the last week of April 1917 I had the good fortune to be asked 

 to accompany Messrs. Aird (Waterworks) and Stevens (Inspector of Fisheries)
