1916] The Ottawa Naturalist Si 



gations at the Biological Station, St. Andrews, New Brunswick. 

 His work now covers a varied field, but it is his Tunicate re- 

 searches that claim notice here. 



In 1908 and 1909 Dr. Huntsman investigated the Ascidians 

 of British Columbia, making a fine collection himself, and 

 having placed in his hands collections made by Professor John 

 Macoun, and by myself and the late Rev. G. W. Taylor, and 

 others. As a result of his studies he was able to publish 

 several papers on these curious creatures, but his most notable 

 memoir: "The Holosomatous Ascidians from the coast of 

 Western Canada," covering over 80 pages of the volume; "Con- 

 tributions to Canadian Biology, 1908-1911," with 12 splendid 

 photographic plates, and issued by the King's Printer, Ottawa, 

 in 1912, is an extensive and thorough record of his discoveries. 

 It has attracted wide attention, and specialists in various coun- 

 tries, from the United States in the west, to Russia in the east, 

 have welcomed this memoir as an umisually important one. 

 Indeed, Professor W. Redikovzew, a distinguished Russian 

 zoologist, has been so impressed by Dr. Huntsman's results as 

 to adopt these Canadian discoveries and conclusions set forth 

 in the memoir alluded to, and has embodied them in a fine 

 paper, in Russian, recently issued at Petrograd. 



Dr. Huntsman's beautiful plates, with precisely 100 

 figures, are heliotypes of his own exquisite photographs of 

 Ascidians. They are so skilfully done that the most minute 

 structural features are shown with marvellous delicacy and 

 faithfulness. The descriptions in the text are clear, accurate, 

 and models of scientific exposition. Important classificatory 

 features are given in graphic tabular forms, inserted under each 

 species, and summarizing measurements, and other details. 



It is impossible here to do more than indicate some of Dr. 

 Huntsman's results. They embrace the following families: 

 The Perophoridae ; the Family Agnesiidae, with one species new 

 to science; the Chelysomatidae, three new species; the Caesiridae, 

 four new species; the Styelidae, five new species, including, in- 

 deed, a new genus, Chemidocarpa, and one new species Met- 

 afldfocarpa Taylori, appropriately named after the late Rev. 

 Mr. Taylor, who did herculean work as a pioneer in Pacific 

 zoology; and, finally, the Family Tethyidae. In view of our 

 extended knowledge, due to Dr. Huntsman's researches, the 

 last-named Family has acquired a new significance, and one 

 of the genera, Boltenia, has changed its application. Very in- 

 teresting facts are to be noted regarding the geographical dis- 

 tribution of these sedentary forms. The two species B. ovifera, 

 of the eastern shores, and B. villosa, of the Pacific shores, meet
