well-documented localities than from one given simply as Cretaceous 

 of Texas or fossil from Italy. 



Furthermore, the original publication should state definitely which 

 specimen is the holotype, or other primary type, give exact data as to 

 locality and horizon, and also state in what institution the types are 

 deposited and list the catalog numbers if such are available. 



GENERIC DIAGNOSES 



Genus BRACHYSIPHON Chapman, 1906 



Plate I, figure i 



Original description. — New Zealand Inst., Trans. Proc, vol. 38 

 (21st of n, s.), pt. 2, art. 17, p. 83, 1906. 



Type species. — Brachy siphon corhulijonnis Chapman, 1906. Orig- 

 inal designation ; monotypic. 



Diagnosis. — Test free, elongate, cylindrical ; wall agglutinated, incor- 

 porating numerous small Foraminifera and other shell fragments, as 

 well as sand grains, on a "chitinous" base or internal lining ; aperture 

 an irregular opening at the slightly constricted end of the tube. 



Types.— Or{gm2i\ types from lat. 36°8' S., long. 175° 55' E., off 

 Great Barrier Islands, North Island, New Zealand, at no fathoms 

 depth, and are probably in the Melbourne Museum. The figured speci- 

 men is a topotype in the Sidebottom Collection, B.M.N.H. No. ZF 

 3572, from off the Great Barrier Islands, New Zealand. 



Discussion. — Cushman (1948, p. 78) stated that this genus was 

 possibly synonymous with Proteonina Williamson, 1858. As has been 

 shown elsewhere in this article, Proteonina Williamson is synonymous 

 with Reophax and hence quite unlike Brachysiphon. 



Brachysiphon differs from Saccammina M, Sars, 1869, in the elon- 

 gate cylindrical form and from Lagenammina Rhumbler, 191 1, in the 

 parallel sides and in lacking a constricted neck. It superficially re- 

 sembles a Bathysiphon, but is closed at one end and much shorter. 

 Galloway (1933, p. 74) stated that it was as wide as long and with a 

 proloculum at one end, but these statements are not borne out by an 

 examination of the topotypes in the British Museum.
