14 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 128 



record the species from Discovery station 363 at 2.5 miles S. 80° E. 

 of the southeast point of Zavodovski Island, South Sandwich Islands, 

 at 329 to 278 meters depth. 



Discussion. — Heron-Allen and Earland included this triloculine 

 species with their quinqueloculine arenaceous forms in the genus 

 Miliammina. However, in view of the distinctive chamber arrange- 

 ments, long considered a valid reason for separation of the calcareous 

 Miliolidae, we here consider the triloculine species to belong to a sep- 

 arate genus. Miliammimi oblonga Heron-Allen and Earland forma 

 sdbulosa Rhumbler, 1936, is apparently also a typical Trilocularena 

 and should be referred to Trilocularena sabulosa (Rhumbler). 



Genus HAUERINA d'Orbigny, 1839 

 Plate 2, figure 2 



Original description. — In Ramon de la Sagra, Histoire physique, 

 politique et naturelle de I'lle de Cuba, p. 38, Paris, 1839. 



Type species. — Hauerina compressa d'Orbigny, 1846. First species 

 published in the genus. 



Diagnosis. — Test free, compressed, equilateral, subcircular in out- 

 line, early stages quinqueloculine, later planispiral with three or more 

 chambers to a whorl ; wall calcareous, porcellaneous, imperforate; 

 aperture a series of pores in a sievelike plate, the trematophore. 



Types. — The holotype (here figured) is deposited in the M.N.H.N., 

 Paris, and is from the Miocene of the Vienna Basin. 



Discussion. — D'Orbigny's original description of the type species 

 stated that it had only an oval aperture, surrounded by numerous 

 tubercles. Later references have stated that the species had a cribrate 

 aperture, but most later references to this species have been misidenti- 

 fications. The species is apparently restricted to the Miocene of the 

 Vienna Basin. The holotype is here described and figured for com- 

 parison with the new genus Involvohauerina. 



The figure shows the keeled form of this species, and a ridge shown 

 to one side of the keel in the figure is the remains of a later chamber 

 that was broken away. 



INVOLVOHAUERINA Loeblich and Tappan, new genus 



Type species. — Involvohauerina globularis Loeblich and Tappan, 

 new species. 



Derivation. — involvo L., to roll up, wrap up -\- Hauerina, patronymic 

 name for de Hauer. Gender, feminine.
