THE VOYAGE OF H.M.S. CHALLENGER. 
Textularia transversaria ; Pavonina Jtabelliformis, Chrysalidina dimorpha, 
Spiroplectci annectens, Cassidulina calabra, Cornuspira sulcata and Cornus- 
pira carinata. 
Station 185 A. — September 7, 1874. Torres Strait, Cape York. Depth, 3 to 11 
fathoms. 
Sand and stones, with fragments of sheds, coral, and the like, all much worn 
and broken. Foraminifera poor ; the genera Operculina, Amphistegina, 
Alveolina, Miliolina, Polystomella, and Rotalia furnishing the principal 
species. 
Station 186. — September 8, 1874. Flinders Passage and off Wednesday Island, 
Torres Strait. Depth, 7 to 8 fathoms ; coral sand. 
The specimens from these dredgings were also a good deal worn. The por- 
cellanous genera furnish the more interesting species, of which are Miliolina 
rupertiana, Miliolina, reticulata and Miliolina agglutinans ; Hauerina 
compressa, Hauerina circinata, and Hauerina ornatissima. A few worn 
specimens of Discorbina vesicularis were noticed, but the principal part of 
the Foraminifera are the varieties of the shallow-water tropical types 
Alveolina, Peneroplis, Orbitolites, Amphistegina, Heterostegina, Operculina, 
Calcarina, and Tinoporus. 
Station 187. — September 9, 1874. Lat. 10° 36' S., long. 141° 55' E; Depth, 
6 fathoms ; coral sand. 
Station 187 A. — September 9, 1874. Off Booby Island, Torres Strait. Depth, 
8 fathoms ; coral sand. 
The material from these two Stations closely resembles that from the two 
immediately preceding, both in physical characters and in the prevailing 
organisms. The Foraminifera are for the most part of the shadow- water 
genera just enumerated. Amongst the less common forms Clavulina 
angularis and Clavulina parisiensis, and the varieties of Miliolina and 
Hauerina , already mentioned as occurring at Station 186, are the most 
noticeable. 
Station 188. — September 10, 1874. Lat. 9° 59' S., long. 139° 42' E. Depth, 
28 fathoms ; mud. 
Sandy mud, with stones and fragments of coral, molluscan shells, Echini, and 
the like. Rhizopod-fauna derived chiefly from the Milioline genera and the 
foUowing, namely, Peneroplis, Clavulina, Bolivina, Pulvinulina, Rotcdia, 
and Polystomella, the rare species being Rotalia papillosa and an allied form, 
and Polystomella subnodosa.
