Professor Flower summed up his remarks on the 

 genua as follows : — 



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

 " Metis, Kurysome, Cy mod ice, Aduncns, and Gilli, some 

 'of which may bd specifically distinct, but, if so, arc very 

 " closely allied, and still require definite elucidation of 

 '■ their characters, the principal differences observed in 

 " the skulls depending on the comparative breadth of tlie 

 ■ rostrum, a chai'acter much influenced by sex. 7' adiiticiis 

 ■■ (Z'. ahtisalam, Gray) differs from the rest onlv in its 

 " superior .size." 



" 2. T. Catalan in, of smaller size than any of the 

 " otners, and with smaller and more numerous teeth. 

 " There is tnith in the remark with which Dr. Gray 

 ■■ concludes his original description. " 



One of the most recent reviews of this genus which 

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

 dard '^> in 1900. lie points out T. tursio is the only 

 satisfactory type of the genus, and gives as apparent 

 synonyms Del phinus trnncatut, Montagu; 1). metis, Grav ; 

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

 provisional remarks, T. catalania, Gray ; 7'. abnsalam, 'Rup- 

 pcll ; T. (jilli and T. parvimanus. 



As regai-ds 7". catalania. Dr. Beddard points out that 

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

 7'. tursio, except that the ^des are covered with blotches 

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

 s|)ici.-s is admitted both by Sir W. Flower and Mr. Ti-ue. 



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

 though 7'. catalania was originallv described from two 

 specimens obtained from the north-east coast of Australia, 

 successive writers have included it as the representative of 

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

 cluded T. fvrsio. We have not had the opportunity 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 

 7'. 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- 

 tjion, but we are of opinion that too much attention
