Among other evidence brought forward by these same authorities, allusion is made to some fragments of a very large Cephalopod contained in the Amsterdam Museum, described and figured by M . Harting in the Memoirs of the Royal Academy of the same city. Having had occasion to refer lately to this contribution of M. Harting's, its value was found to be considerably beyond what was anticipated from the very brief notice taken of it by Crosse and Fischer, its bearings upon the genus Architeuthis being especially important. A description, with three fine quarto-plate illustrations, is here given of fragments of two separate examples-No. 1 being a pharynx and beak with several suckers preserved in the Utrecht Museum, but of which no record has been preserved, and No. 2 comprising also a pharynx and beak with the terminal portion of a sessile arm taken from the stomach of a shark in the Indian Ocean. The fragments of this last example being demonstrated by M. Harting to belong to one of the armed Calamaries, Enoploteuthis, No. 1 alone demands our present attention. This M. Harting identifies with Prof. Steenstrup's Architeuthis dux, he having had the advantage of corresponding with that eminent authority, and having, moreover, compared the fragments described by himself with the plates illustrative of that species prepared, but unpublished, by Prof. Steenstrup. In the same communication M. Harting expresses his opinion that there is not sufficient ground for the institution of this genus Architeuthis, and refers Prof. Steenstrup's typical Architeuthis dux to a species of Ommastrephes, most probably identical with 0. todarus, D'Orb., and with which form the contour of the mandibles and the armature of the suckers strikingly accord. This species, however, is distinguished from all known cuttlefish by the remarkable feature of having its two longer tentacular arms covered with suckers, arranged in four rows, throughout their length; and in the absence of any evidence concerning these arms, the positive identification of this form with Prof. Steenstrup's species could not be arrived at. W e must now return to the evidence adduced by Prof. A. E. Verrill in association with the Newfoundland specimens and with fragments of other examples that have fallen under his personal notice. In all, Prof. Verrill makes mention of five different individuals, four of which, including the two examined by the Rev. M . Harvey, he anticipates to be identical with Steenstrup's Architeuthis dux, and the remaining one to represent the less-known A. monachus. The jaws of this last example are preserved in the Museum of the Smithsonian Institution, and are described by Prof. Verrill as being very thick and strong, with a decided notch and prominent angular lobe on its inner margin ; from a photograph of the same, submitted to him, Prof. Steenstrup also concurs in the probable identity of the example with his A. monachus. Out of the four remaining, which Prof. Verrill refers to A. dux, he 32* N**- |
