An additional collection of cestode material from the Canadian Pacific coastal region comprised Ligula intestinalis, Schistocephalus solidus, Clestobothrium crassiceps, Grillotia erinacea and Proteocephalus arcticus. The common tetrarhynchoid larva of Ophiodon elongatus is identified with Nybelinia surmenicola Okada and some notes upon its biology are given.

The results are given of a survey of the cestode fauna of 1,500 fishes representing 26 species common in the straits of Georgia, British Columbia. The survey yielded only five species of adult and four species of larval cestodes. No cestodes were found in members of the Pleuronectidae and Embiotocidae and—with one exception—the Scorpaenidae, and the rate of infection in other families was singularly low.The cestodarian species in Hydrolagus colliei is regarded as identical with the Atlantic Gyrocotyle urna Gr. et Wag. The common cestode of the Pacific salmon is regarded as Eubothrium oncorhynchi n. sp., closely allied with the European Eubothrium crassum Bloch. Bothriocephalus scorpii Müll. occurred in Leptocottus armatus and Hexagrammos decagrammus, Bothriocephalus occidentalis Linton in Leptocottus armatus and Sebastodes maliger, and Gilquinia tetrabothrius v. Ben. in Squalus sucklii; a redescription is given of the two latter species. The larval forms recorded were two species of Diphyllobothrium in Oncorhynchus, a species of Nybelinia in Ophiodon elongatus, and a species of Phyllobothrium in Oncorhynchus.

The muscle myogens and other components of the spring salmon (O. tshawytscha), chum salmon (O. keta), coho salmon (O. kisutch), and sockeye salmon (O. nerka), as well as the lingcod (Ophiodon elongatus), were separated by the use of diethylaminoethyl (DEAE) cellulose columns. Significant amounts of slowly dialyzable inosine and inosinic acid which may lead to spurious peaks in moving-boundary electrophoretic separations have been shown to be present in the muscle myogen preparations. The basic differences in the muscle myogen components of the Pacific salmon and the lingcod are compared.

Although congenital choledochal cyst, a localized dilatation of the common bile duct, is an unusual condition in many countries, it should be expected in any infant who presents the triad of jaundice, tumor and pain in the right upper abdomen. Not less than 500 cases have been reported in the medical literature. Recently it is pointed out, that the congenital chledochal cyst is more common in Japan than in Europe or American countries. A personal contact with the Japanese delegation attending the meeting of the Pacific Association of Pediatric Surgeons in Vancouver, May 1971, confirmed it.

This study provides an update on the ectoparasites (ticks and leeches) associated with Rhinoclemmys annulata and provides new accounts on the ectoparasites associated with R. nasuta, R. melanosterna andKinosternon leucostomum from the Pacific coast of Colombia. The presence ofAmblyomma sabanerae on R. nasuta and R. melanosterna provided two new host records for the tick species. Also, the documentation ofA. sabanerae from the Department of Valle del Cauca represents a new department record for the species in Colombia. Placobdella ringueleti was identified fromR. nasuta and K. leucostomum, which represents a new host record for the leech species, as well as a significant extension of the known range.

The diet and the feeding habits of the common dolphinfish (Coryphaena hippurus) in the Pacific coast of Ecuador was assessed by examining 320 stomachs of individuals ranging from 51 to 149 cm in total length. Fish was the predominant prey group in the diet (Alimentary Index, %AI = 95.39) followed by cephalopods (%AI = 4.13) and crustaceans (%AI = 0.48). Among the 17 prey items that make up the dolphinfish diet, the Exocoetidae family was the most important prey (%AI = 57.13), Dosidicus gigas being the most abundant invertebrate species (%AI = 7.65). Feeding patterns were evaluated using the graphing method of Amundsen, which suggested that this species shows a varying degree of specialization on different prey taxa. Thus, while some species were unimportant and rare (Hippocampus hippocampus, Lagocephalus lagocephalus, Gobiidae and Argonauta sp.), several dolphinfishes showed a high degree of specialization on Scombridae, Pleuroncodes planipes, Portunus xantusii and Opisthonema libertate. Size-related and temporal shifts in dietary composition were investigated by PERMANOVA analysis, which showed wide variations among size classes and periods of capture. The results of this study indicate that the common dolphinfish is an opportunistic feeder, which is capable of consuming a wide variety of schooling epipelagic organisms.

The development of systematic mathematics requires writing, and hence a non-literate culture cannot be expected to advance mathematics beyond the stage of numeral words and counting. The hundreds of languages of the Australian aborigines do not seem to have included any extensive numeral systems. However, the common assertions to the effect that ‘Aborigines have only one, two, many’ derive mostly from reports by nineteenth century Christian missionaries, who commonly understood less mathematics than did the people on whom they were reporting. Of course, in recent decades almost all Aborigines have been involved with the dominant European-style culture of Australia, and even those who are not literate have mostly learned to use English-style numerals and to handle money. Similar qualifications should be understood when speaking of any recent primitive culture.

The Hague Conference of 1907 is over and the delegates return to their respective countries. Aspirations for the pacific settlement of international disputes have been voiced and a list of possible arbitrators has been drawn up described by the formal name of the Permanent Court of Arbitration. Well and good! No obligation was accepted to have recourse to the Court, but at least the Conference went so far as to declare its acceptance of “the principle of compulsory arbitration” and its applicability to international agreements. At the same time the Conference declared that the divergencies of opinion in respect to compulsory arbitration “have not exceeded the bounds of judicial controversy,” and that the delegates, in the course of their long collaboration, had succeeded “in evolving a very lofty conception of the common welfare of humanity.”
