teeth more uniform in size, the largest being on the outer margin, and 

 the distal suckers bear 18 to 20 teeth largest distally but uniform in 

 regularity. 



The buccal membrane is seven-pointed, and each point bears two 

 to six small suckers. 



The gladius has a broad rhachis; the vane is large, oval, with round- 

 ed margins. 



The color, in alcohol, is yellowish brown with indistinct reddish- 

 purple chromatophores scattered about over the mantle, head, and 

 arms. 



Measurements and indices of five specimens of Loligo edulis Hoyle are :

Discussion. — I have carefully compared the present specimens 

 with well-preserved males and females of L. etheridgei Berry (1918) 

 from More ton Bay, South Queensland. There are many differences 

 in etheridgei, most noticeable of which are : (a) the more numerous and 

 more slender, often pointed, teeth on the arm suckers which gradually 

 reduce in size, (b) the minute teeth on the proximal border of the arm 

 suckers, (c) the more irregular teeth on the tentacular suckers, and 

 (d) the short modified area of the hectocotylized arm. I also had 

 four specimens of Loligo from the fish market, Pusan, Korea, sent me 

 by a former student, Mr. Won Tak Yang, which conform exactly to 

 Sasaki's L. edulis forma nagasakiensis. The present material con- 

 forms closely to the material from Korea, varying only in size and in 

 the reduction in length of the dorsal row of papillae on the left ventral 

 arm as described for nagasakiensis. Sasaki's material came from 

 Nagasaki which lies on the east side of the Korea Strait and below 

 Pusan. After careful study of all the available material, I consider 

 L. edulis to be distinct from L. etheridgei, at least until such time as 

 additional material shows otherwise. The specimens in the lot from 

 Sta. D5376 were labelled Loligo edulis in what I presume to be Dr.
