is to be regarded as full grown. Other di- 

 mensions can not be taken on account of the 

 distorted condition of the respective parts. 



Body and head somewhat contorted and 

 out of shape. Skin largely mutilated and 

 worn off. General form agreeing with that 

 of this species. The same is true of the shape 

 and size of the caudal fin, which exhibits the 

 characteristic outline. Details of head nor- 

 mal. Opening of the lids of the eyes widely 

 distended, irregularly circular, anterior sinus 

 indistinct (this is apparently due to preserva- 

 tion). 



Sessile arms agreeing in size and shape 

 with" this species. All marginal membranes 

 (outside of the suckers) very slightly devel- 

 oped (or worn off), the dorsal and lateral 

 folds of these arms indistinct, and this is 

 especially true of the high median keel of the 

 third arm, of which only traces are seen in 

 our specimen. Owing to the slight develop- 

 ment of these keels all the arms appear less 

 angular and more rounded in cross section, 

 although the typical shape is still indicated. 

 Tentacular arms agreeing completely with 

 this species, only the keel on the back side 

 of the club is less strongly developed. Mar- 

 ginal membranes of the suckers indistinct. 



No hectocotylization on the fourth sessile 

 arms visible; thus our specimen seems to be 

 a female. 



Arrangement, size and structure of suckers 

 of the sessile as well as the tentacular arms 

 agreeing perfectly with Verrill's description 

 and the specimens used for comparison; the 

 only difference I see is that outside of the 

 two rows of large suckers of the club of the 

 tentacles there are only a few smaller ones ; 

 but these may in part have been torn off and 

 lost. 



The buccal membrane agrees with this 

 species. Color, yellowish-white, with purple 

 chromatophores, but skin largely damaged, 

 80 that the usual color pattern is not visible; 

 but the dark blotches above the eyes are well 

 marked. The pen has not been taken out. 



To sum it up, our specimen agrees in all 

 essentials with Illex illecehrosus; the only dif- 

 ferences observed, namely, the wide eye open- 

 ing, the lack or slight development of the 



marginal membranes and the keels of the 

 arms, and the absence of some suckers on the 

 tentacles, are no doubt due to preservation 

 and rough handling. That the latter has 

 taken place is shown by the general abrasion 

 of the skin, and the fact that a large number 

 of the suckers have lost their horn rings or 

 are entirely torn off. Similar mutilations 

 and changes are very often observed in iU- 

 preserved cephalopods. Therefore, I arrive 

 at the conclusion that the present individual 

 is in no wise different from Illex illecehrosus 

 of our northeastern coasts.* 



As to the alleged capture of this species in 

 Onondaga Lake, I can only refer to what Dr. 

 J. M. Clarke says (I. c), and if it is a fact 

 that this species lives in this lake, the only 

 explanation is, as suggested, by a former, 

 post-glacial connection of this lake with the 

 St. Lawrence Gulf. But I am loath to be- 

 lieve that this species lives in Onondaga Lake. 

 In this connection I venture only one single 

 suggestion: this squid is largely used for 

 bait, and the capture of squid forms a regular 

 trade on our northeastern coasts. Could it 

 not be possible that somebody has secured by 

 purchase a barrel of squids, to be used as bait 

 at the locality where our specimen was founds

KALLIMA BUTTERFLIES. 



To THE Editor of Science: Dr. Bashford' 

 Dean will find some interesting remarks on 

 the mimicry by this butterfly, and some criti- 

 cisms of museum representations of it, in an 

 interesting article by E H A ' On the Influ- 

 ence of Mind in Evolution,' Natural Science, 

 Vol. IX., pp. 29Y-302, November, 1896. The 

 main point as regards museums made by this 

 competent observer is that he never saw a 

 Kallima sitting with its apparent stalk to- 

 wards the twig of a tree. On the contrary, 

 it ' always alights head downwards, so as to 

 face anything coming up the tree, which is 



* This species is abundant from Cape Cod to 

 Newfoundland. Rarely it is found to the soiith 

 of this range (Vineyard Sound and coast of 

 Rhode Island).
