234 CALAIS NEWBOLDI FROM THE LEBANON. [May 1 896, 



Length of the largest arms 7 inches, of the shortest pair of dorsal 

 arras 4 inches ; the second or ventral pair of slender arms are 5 inches 

 long. The head with the arms is nearly 10 inches in length. The 

 beak is | inch in length and -^ inch broad at its base. 



At present, so far as my information serves, Calais Newholdi 

 remains the oldest and only known fossil octopod. 



I have retained Mr. J. de Carle Sowerby's original name, it having 

 been already recorded in print by Dr. Oscar Fraas and by Dr. Louis 

 Lartet in their respective works already referred to. 



The genus Calais is derived from Calais, the brother of Zetes (sons of Boreas 

 and Orithyia), frequently called the Boreadse (mentioned among the Argonauts), 

 and described as winged beings. [Smith's Classical Dictionary, 1883.] 



POSTSCRIPT. 



The genus Dorateuthis, proposed by myself in 1883, is by Zittel 

 included in the genus Plesioteuthis of A. Wagner (1860), which has 

 also a tricarinate internal pen with a spatulate distal expansion. 



There are now in the British Museum (Natural History) as many 

 as ten Teuthidse, 1 the largest of which is 20 inches in length, and 

 exhibits the body, head, and arms in union. The smallest is not so 

 large as D. syriacus, H. W. (1883). They all possess tricarinate 

 shells. 



I hope to offer some further notes upon these very well-preserved 

 decapod cephalopoda from the Lebanon later on, with the promised 

 kind co-operation of Mr. G. C. Crick, F.G.S., who has devoted so 

 much attention to the cephalopoda generally, and to whom I am 

 indebted for information and assistance in preparing this paper.

Discussion. 



Mr. Crick: stated that, as the occurrence of this fossil had been 

 already at least twice recorded, and as neither a description nor a 

 figure had been given hitherto, it was most important that the 

 specimen should be described and figured, and it was very fortunate 

 that the fossil had come into the hands of the President for de- 

 scription. He believed the specimen to be a true octopod ; it was 

 therefore the oldest known representative of this division of the 

 cephalopoda.
