Water Lake, N. Dak. One normal specimen measuring 1.98x 

 1.49 inches, and two abnormally small ones measuring 1.75~x.l.33 

 and 1.65.X.1.27 inches. These runts are also abnormal in color, 

 being glaucous green and of a tint much deeper than typical color of 

 most herons' 1 eggs. The shell is also peculiar, being thin and brit- 

 tle and covered witli hundreds of sharp, bur-like granulations, chiefly 

 in a band around the middle. Incubation commenced in the 

 normal egg. 



92. Callipepla gambeli. Gambel'sPartbidge.— April 16, 

 1896. Collected by O. W. Howard, Catilina Mts., Ariz. Nine 

 fresh eggs, exhibiting great variation in size, and showing four 

 distinct types of markings. Nos. 1 and 2, numerous fine dottings 

 and bold blotches of chestnut and milky brown, distributed over 

 the entire surface, with, however, the majority of the bolder 

 blotches on or near the smaller end; Nos. 3, 4 and 5, markings 

 less numerous and seated chiefly on larger half — bold blotches 

 lacking; Nos. 6, 7 and 8, bold blotches most numerous, scattered 

 at random over shell of two, and mostly on smaller end of the 

 other; in addition to the bold blotches there are numerous fine 

 dottings distributed thinly and evenly over entire shell, 1.24x.96, 

 1.31x.98, 1.24X.91, 1.24x.95,1.23x.96, l.lSx.89, 1.14x.90 and 1.20x.94. 

 No. 9, runt; elliptical ovate, ground color evidently dull white, 

 completely covered — save a few places on smaller end where color 

 pigment has scaled off — with fine points of chestnut and olivaceous 

 brown and grayisli, blending from the darker sliade on the smaller 

 to the lighter on the larger end; .65^.51 inch. The eight nor- 

 mal specimens are short ovate in shape, pale clayish- white with 

 a decided buffy tint in Nos. 6, 7 and 8. 



93. Pinicola enucleator. Pine Grosbeak. (Plate IV, 

 No. 93).— July 17, 1896. Collected by O. W. Knight, Bangor, 

 Maine. Three fresh eggs, laid by a captive bird, varying in size 

 and coloration. Ovate to elliptical ovate in shape, and, on the 

 whole, resemble eggs of the Chipping Sparrow on a large scale. 

 Light to deep glaucous- green; one marked with black and fawn 

 color in form of a small irregular wreath around the larger end; 

 on another the markings are confluent in a large circular patch 

 on the larger end, and the black of the former is here broccoli 

 brown; on the third raw umber flakes are noticeable in addition 

 to the other colors and all are seated chiefly in a broad wreath 

 around the larger end; .93x.64, .87^.-63 and .83^.59 inch. 



94. Melospiza fasciata. Song Spabrow. (Plate IV, 

 No. 94).— May 28, 1857. Collected by W. J. Wirt, Gaines, N. Y. 

 Five fresh eggs, four of which are normal and one a runt. In col- 

 oration this runt is abnormal inasmuch as the markings of chest- 

 nut and heliotrope purple are clustered in dense wreaths about eith-
