94 THE NAUTILUS. 



The lower floor of the same building is Prof. Ward's stock of 

 mollusks and invertebrates, one of the largest stocks of shells in the 

 world, classified in labelled drawers, for the convenience of pur- 

 chasers. 



Again we are homeward bound, and are passing the time in show- 

 ing, by turns, the specimens secured, and praising or criticising one- 

 another's acquisitions; but in one thing we all agree — that the 

 instruction and pleasure of seeing Prof. Ward's shells, and the enjoy- 

 ment of a day spent in the company of the Professor and his able 

 lieutenants, is well worth a visit to Rochester. 



NOTES AND NEWS. 



Notes on Unio luteolus Lam. In The Nautilus for Nov- 

 ember last Mr. Geo. W. Dean in distinguishing this species from 

 JJ. radiatus adduces the uniform color of the nacre of the luteolus. 

 This is as a rule quite true. But specimens from the northern part 

 of this State occasionally have the posterior part of the interior 

 tinged with a very delicate pink. In a quite peculiar local form of 

 small size found by Dr. M. L. Leach in Crystal Lake, Benzie County, 

 the tendency is quite marked and nearly every specimen has the 

 rosy tinge to the nacre. I have never, however, seen a specimen in 

 which the whole of the nacre is thus colored, as occurs in U. radiatus.

Strobila labyrinthica var. VIRGO. We have received from 

 Rev. H. W. Winkley of Saco, Me., specimens of a Strobila differing 

 from labyrinthica in being somewhat larger and more depressed, and 

 translucent-white in color, the lip and lamellte opaque-white. This 

 variety was found by Mr. Winkley near Sebec Lake, Piscataquis 

 Co., Maine. — Pilsbry. 



A NEW color-variety of Helix alauda Fer. Mr. Franciscos 

 E. Blanes has lately found, at Maisi, Cuba, a variety of the above 

 species which he proposes to name var. Weeksiana, in honor of Mr. 

 W. H. AVeeks, Jr., of Brooklyn, N. Y. The variety has the follow- 

 ing characters : 



H. alauda color-var. Weeksiana Blanes. Form globose- 

 trochoid with the whorl very strongly deflexed at the mouth. Color 

 pure white with faint oblique pink streaks. Lip bright pink ; aper- 

 ture yellow inside.
