Professor Flower summed up his remarks on the 

 genua as follows : — 



"1. T. tursio, including those that have been named 

 " Metia, Eurysome, Gymodice, Aduncus, and Gilli, some 

 "~ O'f which may be specifically distinct, but, if so, are very 

 " closely allied, and still require definite elucidation of 

 " their characters, the principal differences observed in 

 " the skulls depending on the comparative breadth of the 

 " rostrum, a character much influenced by sex. T adunciis 

 ' ■" (T. ahusalam, Gray) differs from the rest only in its 

 " superior size." 



" 2. T. catalania, of smaller size than any of the 

 ^' otneirs, a,nd with smaller and more numerous teeth. 

 " There is truth in the remark with which Dr. G-ray 

 " concludes his original description." 



One of the most recent reviews of this genus which 

 we have had the opportunity to see is that by Dr. Bed- 

 dard C^) in 1900. He points out T. tursio is the only 

 satisfactory type of the genus, and gives as apparent 

 synonyms Delphinus truncatus, Montagu; D. metis, Gray; 

 D. cymodice, Id.; D. eurynome. He allows, with certain 

 provisional remarks, T. catalania, Gray ; T . ahusalam, Rup- 

 pell ; T . gilli and T . parvimanus. 



As regards T. catalania, Dr. Beddard points out that 

 the species is of small size, and the colour is the same as 

 T. tursio, except that the sides are covered with blotches 

 of darker colour. The beak is also relatively longer. The 

 spe'cips is admitted both by Sir W. Flower and Mr. True. 



We would like to draw attention to the fact that, al- 

 though T. catalania was originally described from two 

 specimens obtained from the north-east coast of Australia, 

 successive writers have included it as the representative of 

 genus foa- the whole Australian Zone, and have not in- 

 cluded T. tursio. We have not had the oppoi'tunity of 

 examining specimens from the type locality and other sec- 

 tions of the Australian coasts, but there can be no ques- 

 tion concerning the occurrence of a Southern form of 

 2'. tursio in Tasmanian seas. As regards the second 

 species, as stated elsewhere, -we hope to gather further 

 material. 



The question of external colouration is worthy of men- 

 tion, but we are of opinion that too much attention
