Dublin Bay fishing-boat. It was named by its discoverer 

 after Professor Owen. Mr. Saxby, of Bonchurch, in the 

 Isle of Wight, had the good fortune to add it to the 

 English fauna. He took a fine specimen near his house in 

 1849. We are not acquainted with any other instances of 

 its capture. Professor Loven records it as an inhabitant 

 of the west coast of Sweden. 



Its body is rather shortly campanulate. The fins are 

 roundish, with broad bases of attachment, and are fixed 

 well up on the sides of the back. The head is large and 

 short, with large bulging eye-protuberances. The arms 

 are unequal, narrowly lanceolate, all except the two lower 

 ones connected together at their bases by a short web. 

 The disk around the mouth is very free from suckers. 

 The tentacles are long and stout, much exceeding the 

 body, and terminated in compressed, crested, lanceolate 

 tips, bearing on their under surface numerous very small 

 suckers, closely set and ranked in as many as six in a row. 

 The suckers on the ordinary arms are large, globular, 

 pedunculate, and have oblique, almost lateral cups. They 

 are ranked in oblique rows of three or four, the two inner 

 ones smaller than those that flank them. Near the bases 

 of the arms the lateral suckers only are seen. The suckers 

 on the two upper arms are more nearly of a size among 

 themselves, more numerous, and smaller than those on the 

 others. The colour of a specimen in spirits is dull pur- 

 plish on the back with numerous minute purple specks, 

 which are seen also on the under side, head, and upper 

 surface of arms. 



Dr. Ball writes to us respecting this animal, — " I had for 

 some hours a specimen of Bossia Jacobi alive. It was very 

 active and watchful. On passing the hand between it and 

 the light, the changes of colour were as quick as thought.
