![important for purposes of comparison. Lastly, I have to thank Mr./W. A. Has well, who has taken the trouble to translate into English my German manuscript. In writing down these remarks, the incompleteness of the research, in many parts, has often struck me; questions which I was not in a position to answer presented thomselves on all sides. Fain would I have filled up these hiati, time, however, would not permit. I allow myself, then, to publish these imperfect researches, since much that is new (the brain of H. Phillipi*, the dentition of H. galeatus) has been gained by this investigation ; and since, in the second place, I cannot tell, on account of my nomadic mode of life, when and where I shall have the oppor- tunity of prosecuting this work further. As regards the material, which has served for the carrying out of this part of the work, for the species H. Phillipi, I have had no lack of material; during the now seven months of my stay in Sydney, I have obtained for investigation, thanks to the assistance of the Hoc. William Macleay and Mr. E. P. Ramsay, seven or eight fresh specimens. No embryos, unfortunately; the youngest animal of this species that I have seen was 225 mm. (8’9 inch) in length, the largest 1010 mm. (4‘38 in.) For the species H. galeatus, I had only one specimen (belonging to the Australian Museum) “ to look at,” as well as a pair of jaws of this shark in the Macleay-Museum. Of the species H. Francisi, I have also had only one specimen “ to look at ”—that preserved in spirit in the Macleay-Museum. ON THE DENTITION OF THE HETERODONTI. 1,—Dentition of the young Heterodontus Phillipi. Bl. The peculiar dental armature of the Heterodonti, assigning them as it does a characteristic and seemingly isolated position * The description of the brain will appear in part III. of my “Contributions to Com- parative Neurology.” [16]](https://iiif.wellcomecollection.org/image/b22367913_0018.jp2/full/800%2C/0/default.jpg)
