Tue Pteropods collected by the ‘ Discovery ’ comprise the following species : — 
l 
Name. Quantity. Locality. 
1. Limacina antarctica, Woodward. Numerous | Winter Quarters, and the region about 
Lat. 61°, Long. 140° E. 
5 
2. Limacina retroversa* (Fleming) . | Moderately abundant | From Long. 95° 43’ W. to Long. 175° 33’ 
| ., and from Lat. 55° to Lat. 61° S. 
| None from Winter Quarters. 
3. Clio sulcata (Pfeffer) . : . | Two specimens and | Lat. 63° 04’ 8., Long. 175° 43'S. 
| some fragments 
4, Clione antarctica, EK. A. Smith | Numerous Winter Quarters. 
5. Spongiobranchaea australis, D’Orb.. Five specimens Winter Quarters, and Lat. 55° 31’ &., 
Long. 156° 19' E. 
Winter Quarters were in Lat. 77° 49’ S., Long. 167° 7’ 4” E. 
* Some naturalists might regard the forms here called Limacina retroversa as at least two distinct species. 
Though ZL. antarctica and Cl. antaretica are represented by numerous specimens, 
and clearly are enormously more abundant than the other species, the quantities 
contained in each tube suggest that they do not occur in such great shoals as the 
northern forms. 
I received the specimens in two consignments, described respectively as Pteropods 
and Pteropods from the Plankton. The former, it would seem, were taken out of 
holes cut in the ice ; the latter in the open sea. In most of the tubes the Pteropods 
are mixed up with other forms, such as small crustaceans, larvee of Lamellariide, and 
a globular gelatinous molluse (probably Lamellaria mollis, E. A. Smith). In the 
majority of specimens the soft parts are well preserved, but the fragile shells are not 
only broken, but partly dissolved by the fluid in which the animal has been killed 
or kept. The number of perfect shells in the collection is small. 
In the above table I have entered Limacina antarctica and Clione antarctica as
