NATURAL - HISTORY NOTES. 
The Pupation of Nymphostola galactina Felder, by J. G. Myers. 
A specimen of the pupa of Nymphostola galactina Felder was taken 
on the 27th October last near the Otaki “ Forks,” fastened by its ter¬ 
minal segments to the upper surface of the leaf of a species of Melicytus, 
which it resembled in its brilliant green coloration. The pupa, which 
was attached to the midrib, projected almost at right angles from the 
surface of the leaf, exposed to full sunlight, on the edge of the bush. 
This position of the pupa, similar to that of numerous butterflies and 
of the plume-moths, has not been previously recorded in the life-history 
of this species. I am indebted to Mr. G. Y. Hudson for the identification 
of the recently emerged imago, and for much kind assistance in other 
directions. 
Note on Two Northern Cirripedes recorded from New Zealand, by 
Professor Charles Chilton. 
In the list given by the late Captain L. S. Jennings in his “ Revision of 
the Cirripedia of New Zealand ” {Trans. N.Z. Inst., vol. 50, p„ 57) two 
northern species are mentioned which were included after some hesitation— 
viz., Balanus crenatus Bruguiere and B. porcatus Da Costa. Mr. H. A. 
Pilsbry, whose exhaustive report on the “ Sessile Barnacles (Cirripedia) 
contained in the Collections of the U.S. National Museum ” (U.S. Nat. Mus. 
Bull. 93) was published in 1916, has been endeavouring to trace all the 
austral records for northern species, and at his request specimens of these 
two species were forwarded to him for confirmation or otherwise of the 
identifications. 
The record of Balanus crenatus was based on three empty shells obtained 
from the hull of the Antarctic exploring-ship “ Terra Nova ” when she was 
docked in Lyttelton Harbour on the 5th November, 1910. After compari¬ 
son of these with specimens from Plymouth, England, Jennings came to 
the conclusion that they veiy probably belonged to the species named, 
and Mr. Pilsbry confirms the identification. 
The “ Terra Nova ” had sailed from England down the Atlantic, calling 
at Trinidad, Cape Town, Hobart, and Melbourne on her way to New Zea¬ 
land, and, as Pilsbry suggests, she had most probably picked up the 
species in northern waters, and it should not properly be included in the 
New Zealand Cirripedia. 
Balanus porcatus was identified by Jennings on specimens from Auck¬ 
land collected by Suter, and others of unknown locality in Mr. V/. R. B. 
Oliver’s collection, though his manuscript notes show that the specimens 
did not altogether agree with the description of the species. Mr. Pilsbry 
finds that the specimens submitted to him belong to Balanus trig onus 
Darwin, as, on removal of the encrustation, they show the colour-markings 
of that species, and one which he dissected has the characteristic “ teeth ” 
on the third cirri as figured in his “ Sessile Barnacles ” (fig. 28). The other 
specimens in Jennings’s collection appear to be the same as those sent to 
Mr. Pilsbry, and accordingly Balanus porcatus should be removed from the 
list of New Zealand species.
