1874.] GIGANTIC CEPHALOPODS. 491 



same article, bestow upon the specimen encountered by the French 

 corvette 'Alecton' between Madeira and Teneriffe the name of Loligo 

 bouyeri, as stated in my earlier communication. 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 plates illustrative of that species prepared, but unpublished, by Prof.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. Halting 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 

 O. 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. 



We 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 Archi- 

 teuthis 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
