hollow cones which are noticed on the under-surface of the horn 
layer drawn otf, are constituted by the pigment-containing, flat and 
stratified cells of this stratum. The deepest lying cells of the horn 
layer are thus sunk somewhat into the upper surface of the stra¬ 
tum mucosum, but under these hollows there cannot be discove¬ 
red any disturbance whatever in the structure of this layer. At the 
bottom of each of the conical indentations there is only found a 
collection of non-flattened epidermis cells irregularly put together. “ 
For the sake of completeness it must further be stated that 
Fjelstrup expressly calls attention to the faet that “an examination 
of the same parts of the skin of the head of the foetus shows no 
trace of anything that might correspond to these pore figures“ — 
for obvious reasons, as is now comprehended. 
Regarding the species of those cuttlefish which have left the 
marks referred to, one can judge partly from the size of the rings 
and partly from the number of the pores. 
Fjelstrup States that the rings had a diameter of 5—15 mm. 
and that the number of pores in each circle varied, according to 
the size, from about 20 to 50. Suckers of such considerable size 
are, however, only found on the so-called „big squids“ {Architeii- 
thus), and the number of pores also correspond well enough, as 
I have counted on Architeiithus-suckQrs of various sizes (3—18 
mm. in diameter) 20 to 55 horny points. 
Jap. Steenstrup has called attention to the faet that it is a 
mistake to believe that it is the cuttlefish known from the coasts 
which serve as food for the Caaing Whale. In the stomach of this 
species of whale, it is horny jaws of Ommatostrephes species 
that are frequently found, together with those of Onijchoteiithidæ 
and similar forms; that is to say, not the jaws of littoral, but of 
oceanic cuttlefish^). 
Now the Architeuthus is just a genus of oceanic cuttlefish. 
And that it has its home in the seas frequented by the Caaing 
Whale is apparent from the faet that several specimens have stran¬ 
ded on the coasts of Iceland and the Faroe Islands, and that a
