一种新的体绿藻，附有安大略省已知物种的注释。作者：E.Nr.沃克，e，。例如，RT。 8.，多伦多，在我的《First I-ist of Ontario Odonata》（CaN. ENr., XXXVIII, r9o6, p. t5t）中，我记录了来自多伦多、De Grassi Point（锡姆科湖）和阿尔冈昆公园的 Somaloc/tlora elongala (Scudd.)，并指出雄性的上肢更多地融入了多伦多和锡姆科湖的例子中比阿冈昆公园的那些。对这些标本的进一步研究揭示了其他区别标记，并让我得出结论，这两种形式是特别不同的，来自阿尔冈昆公园的属于真正的长形，而其他则代表密切相关但显然未被描述的物种。 LTr。我向 E. B. trVilliamson 发送了这两种形式的腹部附肢的草图，他写道，他也拍摄了这两种形式，并且同样认为所讨论的物种是新物种。我向卡尔弗特博士寄去了一份样本，他表达了同样的观点，并补充说他有一对来自魁北克省舍布鲁克的相同表格，由 L'Abbd Begin 拍摄。从那时起，我亲自检查了这些标本。我还通过 NIr 学习了<J。 'illiamson 认为，尼达姆教授（阿迪朗达克水生昆虫，Bull.47，纽约州}ilus.，rgor，499）对 elongala 若虫的描述可能属于同一个新物种。我面前有一个来自同一地点的李约瑟标本，它肯定与我的其他标本相同。李约瑟的附肢模型来自马萨诸塞州剑桥比较动物学博物馆的标本，并且是真正的细长动物。
A NEW SOMATOCHLORA, WITH A NOTE ON THE SPECIES KNOWN FRONT ONTARIO. BY E. Nr. WALKER, e, . e., rt. 8., TORONTO, In my "First I-ist of Ontario Odonata" (CaN. ENr., XXXVIII, r9o6, p. t5t), I recorded Somaloc/tlora elongala (Scudd.) from Toronto, De Grassi Point (Lake Simcoe) and Algonquin Park, and remarked upon the fact that the superior appendages of the male were more inculved in the exarnples from Toronto and Lake Simcoe than in those from Algonquin Park. A further study of these specimens revealed other marks of distinction, and led me to the conclusion that the two forms were specifically distinct, those from Algonquin Park belonging to true elongata, while the others represented a closely allied but apparently undescribed species. ltr. E. B. trVilliamson, to whom I sent sketches of the abdominal appendages of both forms, wrote that he had also taken them both, and was likewise of the opinion that the species in question was new. Dr. Calvert, to whonr I sent a specimen, expressed the same opinion, and added that he had a pair of the same form from Sherbrooke, Que., taken by L'Abbd Begin. Since then I have examined these specimens myself. I also learne<J through NIr. \\'illiamson that the description of the nymph of elongala, as given by Prof. Needham (Aquatic Insects in the Adirondacks, Bull.47, N. Y. State }ilus., rgor,499), probably belongs to the same new species. I have one of Needham's specimens from the same localit,vbefore me, and it is certain)y identical with my other specimens. Needham's figures of the appendages are fi'om specimens in the Museum of Comparative Zoology, Cambridge, Mass., and are those of true elongata.
