3J feet between the tips of the two lobes. The two mandibular 
teeth projected upwards from between the lips at the sides of the 
snout, even when the mouth was shut ; and a bunch of barnacles, 
about 6 inches long, was firmly attached to each tooth. The 
stomach was empty, and appeared very small for the size of the 
animal. 
It is interesting to note that Urafirth Yoe, where this Mesoplodon 
bidens (Sowerby) was caught, is only 4 miles from Hamna Yoe, 
where the specimen of Ziphius cavirostris was obtained which I 
described to this Society in 1872, and for the skull of which I am 
also indebted to Mr. Anderson. 
The following table gives, so far as is known, the sex of the 
different specimens which have been captured, the localities, the 
dates of capture, the naturalists who have described them, and the 
museums where the skeletons, or part of the skeletons, are pre- 
served : —

The circumstances under which this animal has been seen have 
not been favourable for the determination of its external characters, 
as, before it has been examined by zoologists, it has either been 
much decomposed or partially or wholly flensed or dismembered. 
From the several fragmentary descriptions by different naturalists, 
I have compiled the following summary of its external appear- 
ance : — 
Length in adult, 14 to 16 feet. Beak long and slender. Head 
swelling out considerably behind the beak. Body elongated. 
Back dark bluish-grey or slate-coloured, sides lighter, belly whitish.
