 The latter, according to Fischel, attempts to interpret animal coat colors in too simple a way 

 as the product of certain chemical and physical factors, due regard not being given to the 

 morphological evidence on the part played by specialized pigment cells. — Sewall Wright.

1328. Frateur, J. L. La robe sauvage du lapin. [The wild coat of the rabbit.] Reunion 

 Soc. Beige Biol. 1919: 941-943. 1919. — The author finds that crosses between rabbits with 

 the agouti pattern of the wild species, and the black-and-tan variety give agoutis in Fi and 

 a 3 : 1 ratio in F2. The black-and-tan variety is dominant over non-agouti and gives a 3 : 1 

 ratio in F2. He concludes that the so-called agouti factor is complex. In either agoutis or 

 black-and-tans, the white belly may or may not have- a dark undercolor. Dark undercolor 

 is dominant over pure white. — Sewall Wright.

 Zeitschr. Pflanzenziicht. 8: 77-79. 1921. — [Comment on Raum. Weissbliihender Rotklee 

 eine "umschlagende Sippe?" (White-flowering red clover an "ever-sporting variety?" (See 

 Bot. Absts. 9, Entry 1368).] The author presents data given him in a letter by Rimpau, and 

 also data of his own, relative to inheritance of white in flower color in families of red clover. 

 The data are inconclusive because a pure-breeding white-flowered strain of red clover was 

 not certainly secured after several generations, although for a number of generations fertiliza- 

 tion was done by bumblebees enclosed with isolated plants. — L. R. Waldron. 



1330. Gabriel, Cyprien. Sur un cas curieux d'adaptation florale. [A curious case of 

 floral adaptation.] Compt. Rend. Soc. Biol. 83: 1441-1442. 1920. — Attention is directed to a 

 previously overlooked dimorphism of the flowers of Anchusa officinalis. Type A has clear 

 blue corolla 1.3 mm. long by 1 mm. in diameter, relatively infertile anthers, and is visited by 

 bees and flies. Type B has violet corolla, is 2 mm. deep by 1 mm. in diameter, has long well- 

 developed stamens, and is visited by Scolia hortotum. Both types produce nectar but the 

 Scolia can not reach it in type A. The latter type sets abundant seed while type B is probably 

 entirely infertile, serving merely as the source of pollen for A. — Leonas L. Burlingame. 



1331. Gallaud, M. Une lignee de Giroflees a anomalies multiples et hereditaires. [A 

 line of wall flowers with multiple hereditary anomalies.] Compt. Rend. Acad. Sci. Paris 

 171 : 47-^9. 1920. — The author points out that unique examples of monstrosities in these plants 

 have frequently been noted, but that there has been little precise knowledge of the relation 

 of these forms to their parents or progeny. — He has studied 3 successive generations and 

 furthermore has obtained as part of a single plant a large number of anomalies, some of which 

 are already known and others ai'e believed to be new. These are listed as follows: 1. Pluri- 

 cotyl embryos. All seeds have shown this variation in percentages of from 7 to 100. The 

 embryos have 1, 3, 4, or 5 distinct cotyledons, several of which have doubled lobes. — 2. Vege- 

 tative anomalies. These include leaves with many points but with acuminate lateral expan- 

 sions; also many which are undulated and strongly honeycombed. Some stalks manifest a 

 tendency to fasciation with enlarged flattened branches and notable increase in density of 

 leaves. — 3. Double flowers; proliferous shaded petals. Next to the calyx is found a whorl of 

 petals. The axis of the flower is elongated and bears a wreath of 10 or 11 petaloid pieces in 

 2 whorled series, following a novel lengthening of the axis and novel petaloid wreath. This 

 phenomenon is repeated 6 times. All flowers of the stalks are double and sterile. The
