(NH) has been examined by G. L. Voss; it is hard and unmanage- 

 able and its identity cannot be determined. 



The ilhistration reveals nothing that would qualify Chunoteuthh 

 as a bathyteuthid ; the arms and tentacles are too long and slender, 

 no "web" connects the basal parts of the arms, the clubs are too ex- 

 panded, and the arm suckers are too prominent, CMmoteuthiH almost 

 certainly is not a bathyteuthid. 



Unfortunately, Robson's name has to be reckoned with since he 

 considered the specimen a bathyteuthid. The only recourse is to pro- 

 claim Chunoteuthis mlnhna Robson, 1921, a nom^n dubium. 



Thiele (1921) reported on the Cephalopoda obtained during the 

 German South-Polar Expedition, 1901-1903. Specimens of Cfeno- 

 pteryx sicula and Benthoteuthis megalops were included, which he 

 placed in the Benthoteuthidae following Chun and Pfetfer. Two speci- 

 mens 11 mm in mantle length were referred without doubt to B. mega- 

 lops; one was captured in the South Atlantic at 35°10'S, 02°33'E, 

 while the other came from northwest of Prince Edw^ard Island at 

 43°04'S, 36°22'E. A third specimen was questionably referred to this 

 species; it was taken south of the Cape Verde Islands at 05°27'N, 

 21°41'W. 



Naef's work on fossil cephalopods (1922) included a classification 

 of both fossil and Recent cephalopods. The family Bathyteuthidae 

 was listed as the first family under the suborder Metateuthoidea 

 Oegopsida Naef, 1916. The genera Bathyteuthid and Ctenopteryx were 

 listed. 



Grimpe (1922) erected several new taxa in association with the 

 Bathyteuthidae. He listed as the first group in the oegopsids Bathy- 

 teuthina, a new "family group" that included the Bathyteuthidae 

 Pfeffer, 1900. In addition, he erected two new subfamilies, the 

 Ctenopteryginae and the Bathyteuthinae. The former contained only 

 Ctenopteryx^ while the latter included Bathyteuthis and Indoteuthis 

 Grimpe, 1922, p. 45 (an improper replacement name for Chunoteuthis 

 Robson, 1921 ; see discussion under Grimpe, 1925). Grimpe considered 

 that it might be a juvenile Bathyteuthis. No diagnoses are given for 

 the new taxa. Grimpe gave the distribution of species in seas around 

 Europe. B. abyssicola is recorded from the northwest Atlantic and 

 from the Mediterranean with question, apparently querying Pfeffer's 

 (1912) record. 



Naef's monograph (1923) has devoted a chapter (p. 251) to the 

 Bathyteuthidae that includes a detailed diagnosis and discussion of 

 the family, a generic diagnosis of Ctenopteryx^ and a detailed descrip- 

 tion of C. siculus. Apparently Naef had no specimens of Bathyteuthis 

 abyssicola, for he referred readers to Chun's (1910) coverage, upon 

 which he must have relied heavily for his information about the genus.
