“Albatross.” 
It may be added that specimens with the frontal plate more or less expanded, 
thus the typical 2. diomedeae sens. Ortmann, were found among the material 
from the following Stations: — 4619, 4635, 4721, and 4742. 
To the description given in the ‘‘Siboga’”’ Report a few notes may be added. 
The figure of the anterior part of an animal of the typical #. diomedeae Ortmann 
exhibits the enormous expansion of the frontal plate with the reduced rostrum. 
The great majority of the ‘‘ Albatross’? specimens agree completely with the 
‘“‘Siboga’’ specimens in having the short frontal plate developed nearly as in 
E. recurva, and the rostrum slender and about as long as the distal joint of the 
eye-stalks, but in some few specimens, most of them males, the frontal plate is 
quite enormous, very long and extremely broad, covering almost totally the 
eye-stalks; while the rostrum is very short, the plate has the front margin semi- 
circular, and its surface is somewhat vaulted above each eye-stalk. Some other 
specimens show the frontal plate and the rostrum intermediate in size and shape 
between the two kinds of specimens mentioned; among the large number of 
specimens from Sta. 4619 I have found scarcely half a score showing every stage 
between the common form with the short and small frontal plate and a form 
similar to that exhibited in fig. 4a. In all other features and in the structure of 
the copulatory organs the specimens with the greatly expanded frontal plate 
agree completely with the common form. Ortmann established his 2. dicmedeae 
on a couple of specimens with the frontal plate exceedingly large, but according 
to my experience I must consider this development as an anomaly, taking
