^Balcena hiscaymisis. Prof, van Benedeii makps observations on the geo- 
graphical distribution of this species, on the occasion of the discovery of a 
rib at Fumes in Belgium. L. q. 1867, xxiii. pp. 
Balcenoptera, Hr. G. O. Sars examines eritieally the external 
and internal cliaracters which liave been used for the distinction 
of the species and divisions (Vidensk.-Selsk. Forhandl. 1868, 
pp. 31-74). He comes to the conclusion that many of them 
were merely individual variations, and partly dependent on age, 
and determines the specimens described by previous authors 
thus : — 
1. Lofoten Whale (Sars, 1866)= i?. musculus, mas jun. 
2. Christiana Whale=iB, musculus, ]\m. 
8. B. arctica (Schlegel) = -&. musculus, mas jun. 
4. Physalus antiquorum (Gray) = B. musculus, mas adult. 
6. Physalus duyuidii of 60 feet (Gray)=-Z?. musculus, fern. med. aet. 
6. Physalus duyuidii of 46^ feet (Gray) = -B. omisculus, mas med. set. 
7. Balcena tripennis, qiue rostnmi acid, hahet, et plicas in ventre (Sib- 
bald)r=^. musculus, mas med. aet, 
8. Baleinopth'e d bcQ (Ravin) =7?. musculus, mas jun. 
9. Balcenoptera carolince (Malm) may be really a distinpt species, dis- 
tinguished from B. musculus by its size. 
10. Baleine BaUenoptera giyas, fern. 
11. Kepokaruak of Balcenoptera giyas, fern. 
12. Balcenoptera tenuirostris = Balcenojjtera giyas, fern. jun. 
13. Balcena tripennis, quce max. infer, rotundam et super iore multo latiorem 
hahet (Sibbald) = Balcenoptera giyas ?, mas. 
14. Balcena rostrata Balcenoptera laticeps (Gray), fern. jun. 
16, Balcena rostrata {YdLv.,'llvcniQv) — Balcenoptera rostrata, fern. jun. 
16. Beleinopth'c museau-pointu (Lacep,) = rostrata, fern. jun. 
17. Balcenoptera acido-rostrcda = Balcenoptera rostrata, fern. 
jun. 
18. Balcena lonyimana (Rud.) ^ Megaptera lonyimana, mas. 
^Balcenoptera sibbaldii. Prof. Reinhardt has carefully examined notes made 
by Hr. Hallas and captains of whaling-vessels on a whale found in the sea 
round Iceland, and called Stej'pireyor ’’ by the Icelanders. He had also re- 
ceived from them a skull (without mandible), atlas, and hyoid bone, of which 
he gives a detailed description, illustrated by woodcuts. He comes to the 
conclusion that it is the sibbaldii. Ho also states the reasons 
which induce him to refer the Tunnolik ” of the Greenlanders to this spe- 
cies, He agrees with ]\Ir. Flower [see Proc, Zool. Soc. 1868, pp. 187-189] 
that Malm’s B. carolince is most probably the same species. In conclusion, 
he adds the measurements of a male foetus of the ‘‘ Steypireyor.” On this oc- 
casion the author also expresses his views as regards the genera of Fin- 
Whales lately proposed, which he regards as rather superfluous. Vidensk.

^ Balcenoptera rostrata. Messrs. Carter & Macalister have given a very de- 
tailed description of a female 14 feet long, and of its anatomy. Philos. Trans.
