These specimens, though the mantle-length is only some 5 mm., show dis 
tinctly the characteristic form of the articulation with the base of the siphon. 
SYMPLECTOTEUTHIS. 
Symplectoteuthis Pfeffer, : 00, pp. 178, 180. 
This genus has recently been created by Dr. Pfeffer for the reception of the 
speeies named below, on account of the fusion of the mantle with the base of 
the funnel on either side. i

Symplectoteuthis oualaniensis Pfeffer, : 00, p. 180. 
Habitat, — Station 3363, east of Cocos Island (surface tow-net) ; February 
26, 1891; lat. 5° 43° N., long. 85° 50% W., 978 
fathoms ; white globigerina ooze ; temperature, sur- 
face 839, bottom 37.°5 ; one specimen. [H. 53.] 
The funnel groove (see Figure 7) somewhat re- 
sembles that figured by Steenstrup (80, p. 81) for 
Todarodes sagittatus and Ommastrephes pacificus ('80, 
p. 79, Figs. 4, 5) except that the area occupied by 
the cutaneous folds is very much narrower. In this 
respect it differs from the original drawing by Les- 
Fra. F. Funnel groove of 800 (29, Plate 1, Fig. 2) of his L. owalaniensis, 
Symplectoteuthis oualani- where the funnel groove is shown as though it were 
ensis, striated all over,

Rhynchoteuthis Chun (: 03). 
Habitat. — Station 14; Pacific Ocean, north of the Marquesas Islands; Sep- 
tember 7, 1899; lat. 6? 41^ N., long. 137? W. ; temperature, surface, 82°; taken 
at the surface ; one young specimen. [H. 134.] 
Professor Chun’s re-discovery of the curious immature form described by 
Souleyet (52, p. 17, Plate 1, Figs. 15-21) is of extreme interest, and although
