VI. — Brief ^Notices. 



1. New Pekiodical. — The tirst volume of the Memoires de I'Institut 

 Geologique de I'Universite de Lonvain, published under the 

 editorship of Henry de Dorlodot, has recently a})peared. A quarto, 

 printed in large type and well illustrated, it makes an imposing 

 volume. It contains three papers: Asselbergs, " Le Devonien 

 inferieur du Sud-Est de I'Ardeune Beige"; Salee, " La groupe des 

 Clisiophyllides"; and Wong Wen-Hao, "LaPorphyrite quartzifere de 

 Lessines." Other volumes will appear according to material in hand. 



2. Tkiassic Fauna or Inuia. — Diener has published in Palceonto- 

 logia Indica (n.s., vol. v, No. 1, 1913) a memoir on the Triassic 

 Faunae [s/c] of Kashmir found by Middlemiss in 1908 and 1909. 

 This fills up a gap in the Indian series, and provides many additional 

 forms for comparison and study. A full description of the stratigraphy 

 was given by Middlemiss in his memoir on the Silurian-Trias of 

 Kashmir in the Records Geol. Surv. India, vol. xl, 1910. 



3. New Zealand. — The geology of the Aroha subdivision of 

 Hauraki, New Zealand, forcibly brings to notice how much detailed 

 work remains yet to be done before we can form definite maps of 

 the country. This is a large quarto by ]\Iessrs. J. Henderson and 

 J. A. Bartrum, and forms No. 16 Bull. N.Z. Dept. of Mines, 

 Geol. Surv. Branch, 1913. Dealing with Climate, Flora, Fauna, 

 Population, Industries, and Geography as well as Rainfall, this memoir 

 though called geological is quite comprehensive in its view. Previous 

 literature is carefully listed and the views of previous writers 

 properly attended to, and the authors throw the whole of the 

 sedimentary rocks into Jura-Trias with the exception of the various 

 'Recent Deposits'. The large series of Andesites, Dacites, and 

 Rhyolites are described, and much attention is naturally paid to 

 the mining portion of the area. A chapter on Economics closes 

 the Bulletin, which is accompanied with several clearly printed 

 geological maps. 



4. Flokida and other Coral-reef Tracts. — Dr. T. AV. Vaughan 

 having worked for some years on the Floiidian Plateau and included 

 in his observation the Bahamas, Mar(juesas, and Tortugas has issued 

 in the Journ. Washington Acad. Sci., vol. iv, 1914, a " Sketch 

 of the Geological History of the Florida Coral-reef Tract and 

 Comparisons with other Coral-reef Areas". He seems to believe 

 that the final subsidence occurred alter uplift following the close 

 of the Pliocene, and notes that Pleistocene terraces rise to 600 feet 

 in Cuba and 1,000 feet in Barbadoes. The Pleistocene barrier reef 

 on Key Vaca showed 105 feet by boring. 



5. Mod Lumps. — So far as is known the 'mud lumps' of the 

 Mississippi delta are peculiar to that river. The name of * mud 

 lump' has been applied to large swellings or upheavals of tough 

 bluish-grey clay in the territory within a mile or two of each 

 of the mouths of the Mississippi" Many of these mud lumps rise 

 just offshore and form islands having a surface extent of an acre 

 or more and a height of 5 or 10 feet, but some do not reach the 

 water surface. They rise and subside at irregular rates, some 

 suddenly, and constant vigilance is necessary to keep charts of
