finally, the Ammonites- and Trigonia-zones of Cuyler Manor succeed ; and these positions, I believe, will be fully proved upon more mature investigation.
Lower Sundays River. McLoughlin's Bluff, or Prince Alfred's Rest. — I will now describe the Sundays-River strata, commencing with those nearest the mouth of the river, and following up our examination along the course of the stream. The first section is that of a bluff, about a couple of miles from the mouth, which has been named by some of my geological friends " McLoughlin's Bluff," after " mine host" of a small inn*, now called "Prince Alfred's Rest,"

in the plain below. This Section, E (see fig. 3 and Sketch, fig. 2), is the most marked of any I have seen of the upper portion of the " Uitenhage Formation." The rocks of this series appear to be superior to those exposed along the lower banks of the Zwartkops, shown in Sections A & B. Unfortunately, the lower part of the bluff is so thickly covered with brushwood that no definite conclusion could be arrived at with regard to the underlying strata ; but in the water- course of a somewhat precipitous kloof, at a little distance from the bluff (see Section F) was found a lower fossiliferous stratum containing Astarte Herzogii, Trigonia Herzogii, and Pleuromya lutraria. This bed seems to be nearly similar to the stratum No. 11 (fig. 1) on the lower part of the Zwartkops River. Intervening between this and the fossiliferous band marked 5 in this section (F), which bed is evidently the same as that indicated by a similar number in Section E (fig. 3), were sandstones some 250 feet in thickness ; but here, as at the bluff, the brushwood and debris prevented an accurate examination
- Formerly referred to as "McLoughlin's Inn" in the papers by Atherstone
and Rubidge. The fossils from Sundays-River mouth and those from " Prince Alfred's Rest" (or McLoughlin's Bluff) were unnecessarily separated in the paper in Quart. Journ. Geol. Soc. vol. xxiii. p. 170. — T. R. J.
