This small broken specimen agrees exactly, as far as can be made out, with 

 the figures of Adams and Reeve referred to above, and is of about the same size. 

 The specific name gondola has been regarded by Von Martens ('67) and other 

 authorities as a synonym of hians, and this view I have adopted. 



7. Argonauta argo. 

 Argonauta argo Linne', f58, p. 708. 



Habitat. — Station 3371, off Cocos Island ; March 1, 1891 ; lat. 5° 26' 20" N., 

 h)ng. 80° 55' W. ; temperature, surface 82°; two shells, immature; Xo. 8172. 

 [H. 57, 58.] 



Station 2627 Hyd., off Cape San Francisco; March 25, 1891; lat. 0° 36' N., 

 long. 82°45'W. ; temperature, surface 81°; one shell, immature; No. 8139. 

 [H. 59.] 



The three specimens all belong to what Dr. von Martens ('67, p. 104) calls 

 the forma aurita, figured by Ferussac and d'Orbigny ('35, Argonautes, 

 Plate 2, Figs. 4,5). 



8. Argonauta, sp. 



(Plate 10, Fig. 13.) 



Habitat. — 50 miles south of Guaymas, surface ; one specimen 9 • [H. 56.] 

 Station 236, off Arhno, Mar-shall Islands ; January 28, 1900; lat. 6° 34' N., 

 long. 170° 59' E., surface, electric light; temperature, surface, 81°; one 

 specimen 9 [H. 127], one ^ [H. 145]. 



Thase specimens are too young to admit of their being referred to any particu- 

 lar species. The shell of the example from Guaymas (Plate 10, Fig. 12) is 

 interesting as showing the form at this period of development : it is extremely 

 delicate, and hence has been a little chipped at the edge. The dorsal anns 

 show the usual expansion, greatly shrunken and contracted by the action of the 

 spirit.
