. The Conchologists' exchange. Mollusks. THE NAUTILUS. 39 NEW ENGLAND PYRAMIDELLIDJE, WITH DESCRIPTION OF A NEW SPECIES. A very excellent work on the New England Pyramidellidce by Mr. Paul Bartsch has just been published by the Boston Society of Natural History. Specimens from the writer's cabinet were used in compiling this work. Unfortunately there are some omissions. I can blame no one but myself. My excuse is that my specimens were packed and stored, and a few collected later had not been worked up. Hence this supplement. Turhonilla {JPtycheulimelld) polita Verrill. Four specimens (de- termined by Verrill) are in the author's cabinet. The two best ones have ten whorls, and measure mm. They are from Eastport, Maine. Five specimens of Odostomia, collected at Provincetown, have the many lines of trifida hedequensis. They are about the size and shape of the P. E. I. specimens, and probably of that variety. Odostomia {Odostomia') modesta Sumpson. Two excellent speci- mens of this species were found at Provincetown. They are slightly larger than the specimen used to illustrate Bartsch's article. Odostomia bisuturalis. An interesting variety lacking the revolv- ing line, occurs at Provincetown. Mention may be made of three pathological specimens of this species found at the same place. Deep sutures and everted lip, they are one of nature's jokes. Pyramidella (Sulcorinella) bartschi n. sp. Fig. Shell broadly conic, semi-transparent, vitreous. Nuclear whorls small, deeply obliquely immersed in the first of the succeeding turns. BY henry W.
