Beschreibung: Resumen Los autores analizan los resultados générales obtenidos al estudiar los foraminiferos de 29 muestras bentónicas dragadas en la plataforma continental chilena entre 30o y 42o lat. Sur. Las profundidades van desde 12 m hasta 264 m y se incluyeron adernás, varias muestras dei litoral de las bahías de Valparaiso y Concepción. Se registraron un total de 140 especies ‐ 9 de ellas eran planctónicas ‐ pudiéndose subdividir la región estudiada en 2 subprovincias con un límite ubicado entre los 39o y 40o lat. Sur. La fauna es de características ≪templadofrías≫ y el número de especies aumenta con la profundidad; asimismo, él porcentaje de las formas aglutinadas. De las 20 especies descritas por d'Orbigny (1839) en Chile, 12 fueron reencontradas. Las formas planctónicas estan pobremente representadas. Summary The authors analized the general results obtained by studying the foraminifera from 29 benthic samples dredged from the continental shelf of Chile between 30o and 42o southern latitude. The depths are from 12 m to 264 m. In addition various samples from the littoral of the bays of Valparaíso and Concepción were included. The total of species registered was 140 ‐ 9 of them were planktonic ‐ and the studied region was able to be divided in 2 subprovinces with a limit placed between 39o and 40o southern latitude. The fauna is of a ≪temperate‐cold≫ character. The number of species increases with the depth. Also, the same occurs with the percentage of agglutinated forms as compared with the total. Of the 20 species described by d'Orbigny (1839) in Chile, 12 were reencountered. The planktonic species are poorly represented.

Beschreibung: Reference to the records of giant squid of the family Architeuthidae indicate that they are in the coastal waters of insular Newfoundland every third decade, beginning in the 1870's. Concentrated effort has been made to secure any available specimens during the decade of the 1960's. Since 1961 there have been nine strandings and seven of the animals have been secured by the author for study. These represent the first North American specimens to be studied since 1935. Apparently there is one species, Architeuthis dux STEENSTRUP. There is little evidence of a biological basis explaining the cyclic nature of the incidence of A. dux in Newfoundland waters. The majority of strandings occur on the exposed northeast coast suggesting hydrographic conditions being causal.
