Loligo marina, Adams, Geu. Rec. Moll. (1858), pi. iv. fig. 3. 

 Loligo vulgaris, Jeffreys, B. C. v. (18(39), p. 130, pi. v. fig. 2. 

 Loligo Forbesii, Lenz, Jahresb. Coiutn. Kiel, Jahrb. i. (1871), p. 135; 

 Hoyle, Proc. Pliys. Soc. Edinb. viii. (1885), p. 459. 



Anterior part of sides of body and ventral surface painted 

 with long dark markings. Tentacular arms having- the 

 suckers of the central rows scarcely exceeding in size those of 

 the lateral rows either in diameter or height, so that the club 

 looks as if it bore four series of subequal suckers. The disks 

 of the central rows of the tentacular arms are scarcely one 

 third larger than those of the central rows of the third arms ; 

 their horny rings bear numerous pointed teeth all round, 

 usually larger and smaller alternately ; suckers of lateral 

 rows completely set with teeth of equal size. Length of 

 ordinary specimens 2 feet. 



St. Andrews (M'lntoshl), Plymouth {A. 31. JV.), Durham 

 and Northumberland coasts {J. Alder I)', a pen from the 

 Northumberland coast in the Newcastle Museum measures 22 

 inches in length. Firth of Forth {Hoyle). 



Jeffreys reunited Steenstrup's species with L. vulgaris on 

 the ground that the differences might be sexual, quite over- 

 looking the fact that Steenstrup expressly states, respecting 

 Danish examples, " Of both species 1 have only been able to 

 examine the males on our coast." 



16. Loligo marmorce, Verany. 



Loligo marmorcB, Verany, Ceph. Medit. 1851, p. 95, pi. xxxvii. ; Forbes 

 and Hanley, Hist. Brit. Moll. iv. (1853), p. 230, pi. QQQ. fig. 2. 



Off Youghal {Dr. Ball, fide F. & H.). I have not seen 

 any British specimens of this species. 



Mediterranean examples are in my collection from Naples 

 (Staz. Zool.) and Nice [Gal.). 



A mere glance at once distinguishes the form from that of 

 the next species, for while the latter exhibits variation in the 

 proportion of parts of the body, still the body as a whole, as 

 far as I have seen, never assumes the appearance of L. mar- 

 morce, which is distinguished by the much broader fins, 

 generally situated further back, and which, reaching quite to 

 the extremity, give an altogether different look to the animal 

 from that of L. media. The following are measurements of 

 four specimens : — ■
