The types of this species were described by d'Orbigny from the 

 Falkland Islands. His figures show a single chamber with very 

 strong, longitudinal costae, very similar to those in our figure. 

 These costae are blunt as shown in his partial section. In our speci- 

 mens there seem to be distinct and rather coarse perforations between 

 the costae. These are referred to d'Orbigny's species and are from 

 the Falklands at Port William. 



LAGENA MELD (d'Orbigny) 



Lagena melo Cushman, U. S. Nat. Mus. Bull. 104, pt. 4, p. 38, 1923. 



D'Orbigny originally described this species from the Falkland Is- 

 lands, and we have specimens both from the Falklands from Port 

 William, and from station 123, St. Julian, Argentina, which are 

 exactly like the figured spocimens given by d'Orbigny. Most of the 

 figured forms referred to this species are not typical, and many 

 of them seem best referred to Williamson's species, which he figured 

 from off the British Isles. It may be possible that the typical 

 Lagena melo is only to be found in the vicinity of the Falklands and 

 the southern part of South America.

There are a few specimens from Rio de Janeiro Harbor, adult and 



young of which are figured here. These seem to correspond closely 



with the typical form of the species, which is widely distributed in 



the present oceans.
