Cranchia reinhardtii Steenstrup. 



A very beautiful and unusually large Cranchia was taken 

 by Captain C. Eckman the 17th. Oct. 1895 in the Atlantic lat, 

 40° N., long. 32° W. It is a representative of the type Cranchia 

 reinhardti Steenstrup, although in souie respects aberrant from 

 the descriptions; but these differences are without doubt due to 

 its size and age, the specimens described hitherto being small 

 and immature, but this one large and mature. Its length from 

 the aboral margin of the fin to the dorsal point of attachment 

 of the pallium is 46 mm. but the width of the pallial cavity is

hardly more than one third of this measurement. It is thus 

 unusually slender for a Cranchia and resembles a Leachia in 

 shape, (Fig. 1) the more so, as the fins are very large and form 

 together a transverse oval 16 mm. in width and 12 mm. in 

 length. They also extend for half their length behind the aboral 

 tip of the mantle, but the gladius seems to be elongated to their 

 aboral margin. The dorsal row of »pointed papillae» (»Pigge» 

 Steenstrup; »spitze Höcker» Pfeffer) counts 54 in uumber, ^) 

 but the hindmost part of the dorsal keel is smooth. The /\ shaped 



^) The same number which Pkeffer has counted.
