HOYLE : REPORTS ON THE CEPHALOPODA. 



the specimen which has come into my hands 

 differs somewhat from those previously figured, 

 it agrees in the Ommastrephes-like form of tlie 

 connection between the mantle and siphon and 

 the fusion of the tentacles. The main differ- 

 ence is that the tentacles are small and short 

 and are united only for a short distance just 

 above the mouth (see Figure G), whilst in the 

 others these organs are much elongated, are thicker 

 than the arms, and constitute a stout, flexible 

 proboscis, which has suggested the generic name. 

 As this form is clearly specifically different 

 from those figured by Professor Chun, I have 

 ventured to name it in his honor.

Habitat. — Station 33r}S; off Cape Mala; Fel>ruary 24, ISill ; lat. 6°30'ISr., 

 long. 81° 44' W., 555 fathoms; temperature, surface, 83°, bottom 40.°2 : green 

 sand ; one specimen, No. 7967. [H. 52.] 



Station 3388; off Cape Mala; March 9, 1891 ; lat. 7° 6' X., long. 79°4S'W.; 

 1168 fathoms; temperature, surface, 73°, bottom 36° 2'; green globigerina ooze; 

 one young specimen. [H. 533.] 



A colored drawing (Plate 1, Fig. 2) was made when the animal was fresh, 

 and is interesting as showing that the deep red color common to many deep- 

 sea Cephalopoda fades only very slightly under the influence of alcohol, the 

 epeciraen being now almost as dark in hue as the drawing. The mantle in 

 this specimen was 23 mm. long, but it is not so prominent in the nuchal region 

 as shown in the drawing. The head and arms also are figured a little too 

 large.
