Remarks. — It is rather a gamble to 

 describe an Australian Loligo mitil someone 

 having access to the British Museum 

 collections can enlighten us as to what 

 Gray's L. australis really is. The original 

 description is not only meagre, but is 

 sufficiently broad in terms to apply about 

 equally Avell to either of the two or three 

 Australian species of the genus which I 

 have before me at this writing. Fortunately 

 one of these is a specimen from Port 

 Jackson [S.S.B. 488], sent me by Mr. 

 Hedley wiih. a note stating that it was 

 identified at the British Museum as L. 

 australis Gray. Assuming the correctness 

 of the determination, australis must be 

 regarded as altogether different from 

 the " Endeavour " species. 



In size and the general outline of its body, L. etheridgei 

 recalls Pfeffer's figures of L. indica, but diff^ers in the some- 

 what larger fins and different dentition of the homy rings, 

 more especially those of the sessile arms, which in L. indica 

 are said to be squared (" viereckigen ") and only about six 

 in number, though comparison should be made with the 

 notes given by Massy (1916, p. 218-221). Its type locality is 

 Java. I agree with Goodrich (1896, p. 7) that a serious 

 discrepancy exists between the specimens taken by the 

 " Challenger " in the Arafura Sea, as illustrated by Hoyle, 

 and the original description by Pfeffer. 



L. edulis, Hoyle, is a stouter, more robust species. The 

 horny rings of its sessile arm suckers are long, but are 

 described as square-cut and but eight in number. Those of 

 the larger tentacular suckers are said to bear about 20 large 

 teeth, with nearly as many smaller ones in alternation.
