A solitary specimen, well-developed and typical. It is curious 

 that single* specimens of this species have been found at various 

 localities, Heron- Allen and Earland reporting odd examples from 

 four stations in the Kerimba Archipelago, and from the coast of 

 Cornwall.

With regard to this form, Millett writes in the above reference 

 as follows : — " The example figured well represents the normal form 

 with the exception that it possesses a supplementary chamber of a 

 Nodosarian character. This is evidently a monstrosity, otherwise 

 the specimen would have to be assigned to the genus Dimorjphina. 

 This chamber appears to have nothing in common with the fistu- 

 lose extraneous growths so frequently found in the Polymorphina 

 generally, but rare or unknown in the examples from the Malay 

 Archipelago." 



Tliis solitary specimen has the added chamber bent to one side, 

 as seen in fig. i 5. I have broken the test, but luckily the draw- 

 ing was made before the accident occurred. Fig. 16 is from a 

 Seychelles Island specimen. 



As I have also found four excellent examples from Mahe 

 Harbour, Seychelles Islands, 14 fms., it is evident that this form 

 is not a monstrosity, and must be assigned, ^as Millett said, to the 

 genus Dimorphina, so I name it after my old friend.

Except that the orifice is not quite typical, the specimen agrees 

 well with Millett's description and figure. I think the aperture is 

 a short slit, with the central opening slightly oval.
