THE VOYAGE OF THE H.M.S. CHALLENGER.
Foraminifera (Zool. Chall. Exp., part xxii., 1884). From Stations 348 to 352 in the Eastern Tropical Atlantic no specimens of the bottom were obtained, but a rich pelagic Radiolarian fauna was demonstrated by numerous preparations from the surface. The depths are given in fathoms and the temperature in degrees Fahrenheit. In the column describing the nature of the bottom the following abbreviations are used:—
| rad. oz. = Radiolarian ooze (§ 237). gl. oz. = Globigerina ooze (§ 238). r. cl. = red clay (§ 239). pt. oz. = Pteropod ooze (see p. clviii). di. oz. = Diatom ooze (see p. clvii). |
bl. m. = blue mud, gr. m. = green mud, volc. m. = volcanic mud, |
terrigenous deposits (see p. clvi). | |
| r. m. = red mud. |
| (a) | Locality 1. | (b) | (c) | (d) | Relative Abundance of Radiolaria. |
