Pourtalesia paradoæa n. sp. 
This is the most extraordinary of the species of Pourtalesia 
hitherto known. It is nearly related to P. phiale, but differs from 
that species in having the anterior part of the test produced into 
a long and slender neck, at the anterior, somewhat widened, end of 
which is placed the invagination with the mouth. The posterior 
half of the test is much higher and thicker, distinetly keeled above 
and below. Anal snout rather long, a little upwards bending. Spines 
and pedicellariæ mainly as in P. phiale. 
S. of Iceland. 843—912 fathoms. ("Ingolf”-Expedition.) 
Amphipneustes Koehleri n. sp. 
Differs from A. Lorioli Koehler by its low test, which recalls 
that of Abatus cavernosus. The periproct is above the ambitus at 
the truncated, a little reenteringly curved posterior end. The spines 
are coarse like those of Abatus cavernosus. The valves of the 
globiferous pedicellariæ end in two long teeth. 
| In the female the petals are transformed into marsupia, as in 
Abatus. Young ones were found in the marsupia; they did not 
show any trace of a peripetalous fasciole. 
Lat. 539 34' 8. Long. 439 23' W. 160 M. Lat. 54917" S. 
Long. 36? 28" W. 74 M. Off South Georgia. (Swedish South-Polar 
Expedition.) 
The genus Amphipneustes is evidently closely related to Abatus. 
Among the more noteworthy facts to be mentioned in the final 
reports I may only name: the occurrence in the Northern Atlantic, 
S. of Iceland, of Urechinus naresianus A. Ag. and Hemiaster ex- 
pergitus Lovén.
