connected with the typical TJ. pygmaea (figs. 53-56) through Sagrina 

 puIcJiella, D'Orb., but an intermediate condition between it and the 

 feebler dimorphs of the Mediterranean area occurs in the mud 

 brought up by the sounding lead from the Abrohlos Bank ( U. di- 

 morpha)." "Altogether this latter group of forms shows how great 

 the affinity is between the always hyaline Uvigerina and the porous 

 sandy Te xtularia . ' ' 



Brady in the Challenger Report notes the relationships of both Sa- 

 grina pulcliella and *S'. rugosa to the Textulariidae. 



A study of collections from the West Indies and the coast of Florida 

 has shown conclusively that the Sagrina pulchella of d'Orbigny is in 

 reality a Bolivina wliich is widely distributed in that general region. 

 The peculiar apertural characters with the sides somewhat raised 

 could have easily been mistaken for the sort of aperture in d'Orbigny's 

 figure, if the specimen were not seen from the end. With S. pulchella 

 really a species of Bolivina, and as Brady notes S. rugosa is related to 

 Gaudryina it follows that Sagrina, if used at all, must be used for 

 species belonging to the Textulariidae. As the type species is a 

 Bolivina the name Sagrina can not be used unless for a part of that 

 genus. 



The first name that can be taken up for the generic characters of 

 the species noted by Parker and Jones is Siphogenerina Schlumber- 

 ger. Schlumberger called attention to the internal structure, and 

 erected the genus Siphogenerina based on the tubular connecting in- 

 terior.* The genus is related to Uvigerina and Trifarina {Triplasia 

 or Rhabdogonium) and to the group of the Lagenidae with apertures 

 exserted, with a tubular neck and phialine lip.

Description. — Test elongate, composed at least in the microspheric 

 form of a series of chambers arranged tri or bi serially, followed by a 

 later uniserial development; walls hyaline and perforate; aperture in 

 the uniserial portion central and terminal, usually with an elongated 

 neck and flaring lip; interior of the chamber with a tubular connec- 

 tion running from the base of the apertural neck to the lip of the 

 aperture below; wall smooth or ornamented by costae, pits, etc.
