ARCHITEUTUIS. 185 



across ; arms, 6 feet long, their suckers 1 inch in diameter ; 

 upper jaw nearly 4 inches, lower one 3 inches long. 



Portions of the pen were preserved, as well as the odonto- 

 phore ; they seem to agree with Ommastrephes. 



The above dimensions and the figures which we give, arc 

 from a specimen captured November, 1873, at Logie Bay, New- 

 foundland. 



Dinoteuthis probosc ideas. More (of which we have given a 

 detailed account on p. 79), stranded on the Irish coast two 

 hundred years ago, belongs to this species; the power of pro- 

 jecting the beak like a proboscis, which furnishes the generic 

 character, is common to several genera, if not all of the deca- 

 pods. Another specimen taken recently off Boffin Island, W. 

 coast of Ireland, is also referred to A. monachus by Mr. Verrill, 

 although supposed by Mr. More to = A. dux.

This species is based on some jaws, and on rough measure- 

 ments of the remains of specimens not preserved. A pair of 

 jaws obtained from the stomach of a sperm whale, are figured, 

 and show a close resemblance to .4. monachus. They are larger, 

 the length of the upper jaw being 5 inches, and somewhat differ- 

 ent in shape and proportions from that species. The texture 

 of these beaks is firmer, and the lamina are relatively thicker 

 than in A. monachus. The rostrum and most of the frontal 

 regions are black and polished, gradually becoming orange 

 colored and translucent towards the posterior border. It is 

 believed to be the largest described species, measuring 40 feet 



from tail to tentacular extremities. 



Newfoundland. 



A living specimen was cast ashore (Sept. 24th, 1877), during 

 a severe ^ale. at Catalina, Trinity Bay, N. F. After death, it 

 was packed in brine and forwarded to the New York Aquarium, 

 where Mr. Verrill had the opportunity of examining it. It 

 measures 9'5 feet from tip of tail to base of arms ; circumfer- 

 ence of body. 7 feet ; length of tentacular arms, 30 feet ; of 

 longest sessile arms -(ventral ones), 11 feet; circumference at 

 base, 17 inches; length of upper mandible, 5'25 in.; diameter 

 of large suckers, 1 inch ; of eye sockets, 8 inches. The eyes
