entirely concealed by the gums. The skull coiTcsponded in 

 its general form with the figures in Bell's work ; but the 

 rise of the back part of the head is larger in proportion to 

 the anterior rise than in that figure. The skull measures 

 from the snout to the base of the front rise 9 inches ; from 

 thence across the rise to the base of the second rise 1 foot ; 

 from thence across the hinder rise to the neck, 1 ft. 11 

 inches. The length of the skeleton was 17 ft. 6 in.; ver- 

 tebra', 39 ; viz., 2 cervical, 9 dorsal, with ribs ; 20 lumbar 

 and 8 caudal. The skeleton of this specimen is in the 

 Museum of the Hull Philosophical Society.

 cies, under the name of D. So/rerfiieiisis, Blainv. "Tele 

 osscus la machoire superieure est plus courte et in- 

 fininient plus etroite que Finferieure quilarecoit; en outre 

 cette machoire inferieure est arrae a chaque cote et au mi- 

 lieu de son bord d' un seul dent tres fort confirme et di- 

 rige obliquement en arriere. L'orifice de le vent est en 

 croissant dont les cornes sont tournee en avant." — Blaiii.

Catodon. 



The figure of the Sperm Whale in Duhamel, Pes. iv. /. 

 15,/. 3, is good for the form and blower, and has the 

 " taqiiet " marked ; but a fin has been added below, be- 



tween th(^ vent and tail, in the jjosition of the anal fins of 

 fishes ! in /. Tiiis author lias figured and describe<l

Physeter. 



Professor Eschricht observes that it is most important in 

 determining of M. Fabricius Synonyma, to attend to the 

 Greenlanders' names, as they are most accurate cctolof/is/s; 

 he observes (on the authority of Capt. Holbroll), " tliat 

 two of the animals which Fabricius referred to Physeter, 

 viz., the 'Pernak,' which he called P. Catodon, is probably,' 

 and the 'Ardluck,' P. microps, (which Cuvier has thought 

 might be D. gloUceps) is certainly, the Northern sword- 

 fish, Delphitius Orca." Kong. Danshe. Afhandl. xi. 136. 



I may remark, that as far as I can make out the Danish, 

 it appears that the black fish or Balaina microcephata of 

 Sibbald, which I thought might be Ardliik, has entirely 

 esca]ied the notice of Professor Eschricht. I must own, 

 that Fabricius's description will do for Orca gladiator] 

 except that he calls it black, and does not mention the 

 very remarkable white marks of that species, and he only 

 described the lower jaw as toothed. Now the teeth of 

 Orca are not deciduous.
