 Xotes on the visceral anatomy. 



Anatomically, this species closely resembles Desmoteuthis hyperborea. 

 (See Plate XXV, fig. 1.) It has a similar short, thick, compressed, ovate 

 Jiver, with the intestine in a groove along its ventral edge, and the small 

 ink-sac imbedded in its antero-ventral surface. The gills are laterally 

 placed, short, with long lamella?. The heart is small, irregularly tubular, 

 oblique, with four angles or lobes where joined by the principal vessels. 

 The efferent vessels from the gills are long and conspicuous, because the 

 bases of the gills are distant from the heart. 



The alimentary tract consists of a short, narrow rectum, attached to 

 the liver, and ending in a bilabiate aperture, guarded by two slender 

 papilla?; of a long, rather wide, tubular portion, extending back to the 

 base of the caudal fin, and covered, along the ventral side, with lateral 

 rows of clusters of small follicular glands, which, near the liver, diverge 

 into two, separate, large, lateral clusters; posteriorly, where the rows of 

 follicles cease, there is a small, firm, bean-shaped glandular organ, lam- 

 ellose within, probably serving as a gizzard; this is followed by a long 

 tubular, or fusiform, more or less saccular stomach and a csecal append- 

 age, running back nearly to the end of the body ; at its anterior origin 

 this caecal appendage is separated from the stomach by a constriction. 



The testicle is a rather small, slender, lanceolate organ, attached lat- 

 erally, for its whole length, to the side of the erecal appendage. The 

 prostate gland and vesicular seminales have their usual position at the 

 base of the left gill, but they are small and probably not fully developed; 

 the efferent duct extends over and a short distance beyond the base of 

 the gill, and is slender and pointed. The renal organs are very different 

 from those of the common squids (Loligo and Oininastrcphes). The pos- 

 terior part of the anterior vena-cava becomes glandular in front of the 

 heart; there it parts, sending a long, smooth vein to the base of each 

 gill; there each of these veins expands into an ovate renal organ, be- 

 fore joining the branchial auricles. 



Architeuthis Harveyi Verrill. (No. 27; see p. [201].) 



Since the preceding pages were put in type, I have been able to ex- 

 amine the specimen* mentioned on p. [201]. 



This specimen was purchased by Mr. E. M. Worth, and preserved, in 

 alcohol, at his museum, 101 Bowery street. Xew York, where I had a 

 good opportunity to examine it, about two weeks after it had been put 

 in alcohol. 



Although this is more nearly complete than any specimen hitherto 

 brought to this country, the arms and suckers are not so well preserved 



* An account of this specimen, accompanied by a wood-cut, apparently copied from 

 the photograph, was published in "Harper's Weekly*' for December 10. This ligure, 

 though poor, gives a fair idea of the general appearance of the creature as it would 

 look if lying flabby and collapsed on the shore. _ The peculiar appearance of the cau* 

 dal fin was due to mutilation of that organ.
