36 General Notes. 



Britton's 'Manual' I have examined, in company with Mr. Chas. L. 

 Pollard, the specimen in Professor Greene's herbarium stated by him to 

 be the type of Apocynum medium. It agrees in all respects with the 

 plant to which I applied the name, and in no way suggests A. speciosum. 

 The name miUeri Britton is therefore a synonym of medium Greene. 

 The two species in question should stand as follows: 



APOCYNUM MEDIUM Greene.

A fully adult specimen of Ophibolus rhombomaculatus. 



On October 16, 1901, I obtained a fully adult Ophibolus rhombomacula 

 tus, apparently the first to be recorded. The snake was found freshly 

 killed in a farm road a few miles west of Alexandria, Va. It is 1090 

 mm. in length (of which the tail forms 145 mm.), and in color differs 

 so widely from the bright, handsomely spotted immature specimens 

 hitherto known that its identity was not at first suspected. General 

 color above a uniform brown, between the olive and bistre of Ridgway, 

 faintly lightened by the irregular appearance at the surface of the color 

 between the scales. Two dark longitudinal stripes on each side, the 

 first on the fourth row of scales (spreading to third and fifth) the second 

 on the eighth row (spreading to seventh and ninth) ; these stripes con 

 tinuous from slightly behind head to base of tail. In color they are so 

 faintly darker than the surrounding parts that in certain lights they 

 are quite invisible. They are, nevertheless, sufficiently distinct to cause 

 a strong resemblance to the color pattern of Coluber quadrivittatus. 

 Belly olive yellow with the usual dusky blotches. The olive yellow ex 

 tends over the back on the skin between the scales. Lips and entire 

 space between rami pearly gray, thickly sprinkled with brown dots. 

 At first sight the back appears to be quite unmarked, except for the 

 longitudinal stripes, but on close inspection in a very favorable light 

 faint traces of the rhombic spots may be detected, particularly on the 

 tail and posterior half of body. Qerrit S. Miller, Jr.
