 Duas espécies de Trilobitas, Ilomalonolus 

 Oiara e Dahnania Pailuna são descriptas 

 na ultima destas memorias. 



Em 1876 foi feito novo exame do dis- 

 tricto de Ereré por uma turma de ajudan- 

 tes do Professor Harlt, pertencentes á 

 Commlssão Geológica do Brazil, resul- 

 tando dahi a descoberta de depósitos 

 ricamente fossilifères nos rios Maecurú e 

 Curuá. Uma noticia sobre os Brachiopodes 

 colleccionados nesta exploração foi publi- 

 cada pelo Professor Richard Rathbun no 

 Proceedings of lhe Boston Society of Na- 

 tural History, vol. XX, 1878. O seguinte 

 extracto deste artigo, que leva o titulo 

 On the Devonian Brachiopoda of the Pro- 

 vince of Pará, Brazil, indicará o caracter 

 dos depósitos fossiiiferos destas localida- 

 des. «O Professor Hartt descobriu na expe- 

 dição Morgan, em 1870, a interessante 

 localidade devoniana de Ererè nas proxi- 

 midades de Monle-Alegre, nas margens 

 do Amazonas, onde obteve os primeiros 

 fosseis devonianos, achados a leste dos 

 Andes na America do Sul. No anno se- 



of the new species are accredited to Prof. 

 Hartt's manuscript notes. The other fos- 

 sils from the same locality were described 

 in a joint paper by these gentlemen pu- 

 blished in the Annals of the Lyceum of 

 Natural History of New York, vol. IX, 

 1875, under the title « On the Devonian 

 Tribolites and Mollusks of Ereré Pro- 

 vince of Pará, Brazil. In these papers the 

 Ereré sandstone is referred to the middle 

 Devonian and correlated with the Ham- 

 ilton group of New York. Two species of 

 Tribolites viz, Ilomalonotus Oiara and 

 Dalmania Paitiina, are described in the 

 latter of these papers. 



In 1876 a farther examination of the 

 Ereré district was made by a party of 

 Prof. Hartt's assistants on the Geological 

 Commission of Brazil, resulting in the 

 discovery of richly fossileferous depositson 

 t!ie rivers Maecurú and Curuá. A notice 

 of the Brachiopods collected by the survey 

 was published by Prof. Richard Rathbun 

 jU the Proceedings of the Boston Society 

 of Natural History, vol. XX. 1878. 

 The following brief extract from this pape/' 

 entitled, «The Devonian Brachiopoda ov 

 the ProvinceofPará, Brazih williadicate 

 the character of the fossiliferous deposits 

 at these localities. «Prof. Hartt discovered 

 on the Morgan Expedition in 1870, the 

 interesting Devonian locality of Ereré near 

 Monte-Alegre, on the Amazonas, where 

 he procured the first Devonian fossils 

 found east of the Andes in South America. 

 In the following year he visited Ereré 

 and made large additions to his former
