2 bulletin: museum of comparative zoology. 



was first found by the "■ Albatross," but its publication has been antici- 

 pated by the description of au immature example by Dr. H. Fischer in 

 1896. There are six species described as new. I have also proposed a 

 new genus {Pyroteuthis) for the Enoploteuthis viaryaritifera of Euppell. 



In the preparation of the Plates I have utilized a number of water- 

 color drawings made on the expedition by Mr. Agassiz and Mr. Magnus 

 Westergren whilst the animals were still fresh and the colors of life 

 retained. It would be well if this ])ractice had been followed on other 

 expeditions, as the appearance of Cephalopoda changes very markedly 

 after preservation in alcohol. The other figures are based upon my own 

 sketches, carefully made to scale, and in making the finished drawings 

 I have had the assistance of Miss Mabel B. Ede, Miss E. R. Dust, and 

 Dr. J. H. Ashworth. 



In conclusion I have to express my gratitude to Mr. Agassiz for the 

 opportunity of studying such an interesting collectiun. 



I subsequently received a smaller collection made by the " Albatross " 

 during a cruise among the Pacific Islands in 1899-1900, which contained 

 thirteen species, one of which was new to science and forms the type of 

 a new genus, Cirrobrachium.
