GENERAL SUMMARY. 



The present series of Foraminifera very closely resembles, as a 

 whole, that usually obtained from the oolite formation in Europe. 

 The family of the Lituolidae is here represented by a single 

 species of the genus Haplophragmium, of a form especially 

 typical of mesozoic strata. The family of the Textulariidae is 

 represented by a new species each of Textularia and Bulimina, 

 both of which are, more or less, allied to types which have a wide 

 range in time. The family Lagenidae contains the largest 

 number of species, the nodosarines, comprising four genera — 

 Marginulina, Vaginulina, Cristellaria, and Flabellina,— to which 

 fifteen species and varieties are referred, four of which are new ; 

 these have altogether a strong oolite aspect. The polymorphines 

 have three species, belonging to the genus Polymorphina, and 

 have a generally unrestricted range both in time and space. The 

 remaining two species belong to the family of the Rotaliidae, 

 and represent the genera Discorbina and Truncatulina ; these 

 have also a wide distribution. 



Of the Ostracoda there are seven species and varieties, all of 

 which are apparently new. They are comprised within the 

 genei'a Cythere, Loxoconcha, Cytheropteron, and Paradoxo- 

 rhyncha, and are all members of the Family Cytheridae. The 

 new genus Paradoxorhyncha is a peculiar form, in which the 

 carapace resembles Oypridea in certain features, but is, on the 

 whole, possibly allied more nearly to Cytheropteron and Cytlier- 

 ura. Two of the new varieties are referred to specific types 

 Avhich are essentially mesozoic. The remainder ai-e new forms.
