0/ Redlands, California. 



The following brief notices of additional new forms of cephalopoda 

 from the United States Bureau of Fisheries steamer Albatross 

 Hawaiian collections are offered in advance of the publication of the 

 main report. A previous paper on the fauna has appeared in these 

 Proceedings.* 



LAETMOTEUTHIS, new genus. 



Finned Octopods close to Cirroteuthis, but with the paired cirri 

 apparently wanting. The well-developed radula has seven rows of 

 teeth. The xnnbrella is ample as in Cirroteuthis; there is no ''inter- 

 mediate web," 



Type. — Laetmotheutis lugubris, new species. 



LAETMOTEUTmS LUGUBRIS, new species. 



Body large, Irounded posteriorly; a pair of small, transversely 

 elongate fins attached one at either side. Funnel very large. 



Arms long, appearing merely as thickenings in the very extensive 

 umbrella. Suckers large, flattened, distant; placed in a single 

 somewhat zigzag series; paired cirri indistinguishable. 



Beak large and powerful. Radula large and perfect, comprising 

 seven rows of teeth, of which the tricuspid medians are conspicuously 

 the largest. 



Color a dark livid brown (chocolate colored when captured). 



Type.— C&t. No. 214385, U.S.N.M. [S. S. B. 211]. From Albatross 

 station 3904, off the north coast of Molokai. 



Length of right dorsal arm, 430 + mm.; of umbrella between dorsal 

 arms, 300 mm.; of extracted radula, 22 mm. 



This specimen is very fragmentary and was taken from the surface. 

 A second similar specimen was taken at station 3898.
