 are occasionally washed to land at Sunday Esland.

A very small female without a shell fS. S. B. 420] collected by 

 Bell in 1910 is presumably the same species as the specimens already 

 reported in the paper cited. A photograph of one of the former 

 specimens, showing the hectocotylus in situ within the mantle 

 cavity of the female, is now given as fig. 1 on Plate VI. 



Oliver (1915, p. 500) suggests that these specimens are to be 

 referred to .1. nodosa Solandcr.

As this species has not been figured, the matter is remedied by the

One specimen was dredged off the Kermadecs in 630 fathoms by 

 the Challenger, and reported by Hoyle as the Atlantic M. verrucosa 

 (Verrill). I have long felt grave doubt- as to the correctness of 

 Hoyle's determination. The Kermadec Islands and the eastern 

 coast of the United States are localities so extremely remote and 

 isolated from one another, that such an anomalous distribution for 

 a crawling, bottom-loving species of this sort seems " priori at leasl 

 doubtful. Fortunately we have Hoyle's express statemenl that the 



Challenger specimen "has the extremity of the hectocotylized arm
