Lamarck, which is given first and must therefore be regarded as the 

 typical form of the species, is the one to which he has attached delle 

 Chiaje's name todanis. The name sagittata being therefore invahd for 

 this form, the earUest available is coindeti given to it by Verany ['39, 

 p. 94] in honour of Dr. Coindet, of Geneva. The genus Illex was 

 created, with this species as its type, by Steenstrup ['80, p. 90] for 

 those forms which have the funnel groove without folds and the ten- 

 tacles without connecting apparatus. 



Todaropsis eblanae. — The species was described by Ball ['41, 

 p. 363] as a Loligo, and was regarded by Jeffreys as one of the sexes of 

 his Ominastrephes sagittata (= /. coindeti). The genus Todaropsis 

 was established by Girard ['90, p. 204] for a new species 7". veninyi, 

 from the Portuguese coast. At present the genus includes only these 

 two species, and I do not feel at all sure that they may not be 

 identical. 



Architeuthus.— Norman ['90, p 478] has collected the recorded 

 occurrences of specimens of this genus, but the specific identifications 

 are involved in some uncertainty. The name is very commonly mis- 

 spelt Architeuthis ; Steenstrup ['81, p. i, footnote] explains that it is 

 derived from rev^o's, used by Aristotle for a larger and stronger kind of 

 squid than reu^i?, and therefore the form adopted by him must be 

 maintained. 



LoligO forbesi. — This is the ordinary British Loligo, which Jef- 

 freys did not distinguish from the Mediterranean L. vulgaris. The 

 points of distinction have been given by myself ['85, P- 459] and by 

 Norman ['90, p. 480]. It is quite possible that L. vulgaris does occur 

 on our southern coasts, and a careful watch for it should be kept by 

 marine zoologists in that region. 



Loligo marmorae was regarded by Jeffreys as a variety of Z. media. 

 It is, however, a good species. The distinctive characters are given 

 by Norman ['90, p. 482]. 



Sepia orbignyana.— A great amount of confusion has arisen 

 between this species and the next, in consequence of the name elegans 

 having been applied by different writers to two quite distinct forms. 

 The species now under consideration was named by F^russac in 

 1826 [d'Orbigny, '26, p. 66]; the name 6". elegans de Blainville was 

 adopted for it by Verany ['51, p. 70] in his beautifully > illustrated 

 monograph, and after him by Jeffreys, who, however, correctly states 

 that it is the same as S. orbignyana Ferussac. 



Sepia elegans. — This species was first created by d'Orbigny in 

 1826, in the legend of one of the plates of his "Cephalopodes aceta- 

 buliferes" [Fer. & d'Orb., '35, pi. 8, figs. 1-5], and subsequently further 

 defined in the text of the same work in 1848 (p. 280).
