seen, and have to do with organs of estabHshed dependabihty 

 ior their taxonomic value in this group of S^juids. The 

 hectocotyhis of Enoploteuthis does not appear to have been 

 previously figured, though that of E. clmnii has been briefly 

 described by Sasaki (1916, p. 91). 



As in the present instance all the specimens were obtained 

 in the same general locality, nothing is kno^vn concerning 

 their distributional limits or the faunal region to which they 

 properly belong. 



To judge from the size and abimdance of the photogenic 

 organs this little squid must be brilliantly luminous in life. 

 It is the most graceful and attractive Cephalopod in the 

 " Endeavour " collection, in fact one of the most beautiful 

 of the entire known Australian fauna. 



The species receives its name from a fancied resemblance 

 in the arrangement of the numerous photophores on the 

 ventral aspect of the body to the stars of the Milky Way or 

 Galaxy (Greek ^ia\ii^t'(t<). 



Family HISTIOTEUTHID.^. 

 Genus Calliteuthis, Verrill, 1880. 



CaLLITEUTHIS MIRANDA, Sp. 710V, 



(Plates Ixi.-lxii.) 



Animal of moderate size, of the form characteristic of the 

 genus ; the Body short, robust, broadly conical in outline, 

 widest at or near the anterior margin, thence tapering rapidly 

 to a stout point ; mantle tliick, its anterior margin rounded, 

 with an anteriorly projecting sinuosity in the nuchal region 

 and obtuse points at either side of the funnel, between the 

 latter barely emarginate. Locking apparatus of the usual 

 form, the fumiel cartilages large and possessed of an unusually 

 deep median excavation. Fins short, broad, semicircular ; 

 about 43/100 as long as the mantle, each separately about 

 half as Avide ; meeting and fusing in the median line behind 

 at a point well above and in front of the free tip of the body, 

 which latter their indented margin slightly exceeds pos- 

 teriorly. 



Head enormous, strongly asymmetrical, though the normal 

 deflexion of the axes of the head and body cannot be ascer 

 tained from the present material. Eyes large, strongly asym- 

 metrical ; right eye well developed, but the left extraordi' 

 narily so (PL Ixii., fig. 1), its aperture approximately twice 

 the longitudinal diameter of the right eye-opening, its lens 

 22.3 mm. in diameter, that of the right eye 12.3 mm. ; just
