236 TEUTHID^. 



ill Dublin bay, in 1S36, and afterwards in the same lo- 

 cality by Dr. Ball, and in Belfast bay by Mr. Thompson. 

 It was described under the above name by Dr. Ball, who 

 called attention, also, to the characters which enable us to 

 assign to it its true generic position. 



Its body is very short as compared with other species of 

 the genus, and is somewhat urn-shaped. The fins occupy 

 about three-sevenths of its length ; they are widely trian- 

 gular, and exhibit in their conjunction, an elliptical con- 

 tour. The head is short, broad, and somewhat depressed 

 above. The arms are rather slender and tapering ; the 

 two lateral pairs longest. They bear remarkably large 

 pedunculate suckers, two-ranked and set well apart. The 

 inferior laterals are crested externally. The tentacular 

 arms are very stout, but have their peduncles quite bare ; 

 they are long, and extend below the tail ; their clubs are 

 furnished centrally with two rows of few and very large 

 suckers, flanked by a few r alternating small ones ; their ex- 

 tremities are compressed, crested above, and bear below 

 two or three rows of minute suckers on long peduncles. 



The length of the original specimen is ten inches, in- 

 cluding arms and tentacles. The body is 3*1 inches in 

 length ; the head ] *6 ; the longest arm three inches ; the 

 tentacles six inches. The fin is 1*3 inches in length, and 

 three inches in breadth. The pen is narrow, three-ribbed, 

 and is spatulate at the extremity.
