Report on the Scientific Results of the Exploring Voyage of H. 21. S. Challenger, 1873-'76, 

 Zoology, XIX, Part iv, 1887, pp. 1-74, Plates i-ni. 



General revision of the Pteropoda G-ymnosomata, or naked Pteropods, for which water-color 

 drawings taken from life and alcoholic specimens of various species were furnished to the 

 Royal Museum of Natural History, Brussels, Belgium, for the use of M. Pelseneer. It should 

 be noted that by neglecting to use the drawings and depending on diagrams prepared from 

 specimens preserved in spirits, grave errors of form and proportion have been introduced into 

 the plates of this work. The wing-like processes which give the Pterojjods their name, shrink 

 out of all proportion when immersed in alcohol. In the case of Pneumodernion paclficum the 

 "wings" are 8.3™"" long by 6""» wide in a specimen 16""" in length of body. In the plates 

 referred to, the measurements would be 4.2""" long and 3.1""" wide. For this extraordinary 

 misconception the drawings, accurately made from life and famished by the U. S. National 

 Museum, should not in any way be held responsible.
