 mature investigation. 



Lotver Sundays Rivev. MeLoughlin's Bluff, or Prince Alfred's Rest. 

 — I will now describe the Sundays-Eiver strata, commencing with 

 those nearest the mouth of the river, and following up our exa- 

 mination 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 " MeLoughlin's Bluff," 

 after " mine host" of a small inn*, now called " Prince Alfred's Eest,"

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 " Ui- 

 tenhage 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 fossUiferous stratum contain- 

 ing 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 fossihferous 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 "MeLoughlin's Inn" in the papers by Atherstone 

 and Rubidge. The fossils from Sundays-River mouth and those from " Prince 

 Alfred's Eest" (or MeLoughlin's Bluff) were unnecessarily separated in the 

 paper in Quart. Journ. Geol. Soc. vol. xxiii. p. 170. — T. E. J.
