mander was a male, I examined it with care, but found that it was a 

 female with well-developed ovaries containing ova of various sizes. 



4. The Colors of a Living Speci?nen of the Loiver Californian 

 Boa, Lichanura trivi?'gaia. — The California Academy of Sciences 

 recently received, through Mr. F. Billa, a fine specimen of the 

 Lower Californian boa, collected near San Jose del Cabo. This 

 specimen shows beyond doubt that Lichanura trivirgata is perfectly 

 ■distinct from L. roseofusca of northern Lower California and 

 southern California and Arizona. It agrees in coloration with the 

 specimen still in the Philadelphia Academy of Natural Sciences. 

 The snout is strongly protruding. The diameter of the eye is one- 

 third the distance from the orbit to the end of the snout. The 

 true loreals are two on the left and three on the right side. Scale 

 rows forty- one. Gastrosteges two hundred and seventeen. 



The following description of its colors was prepared while the 

 snake was yet alive : 



Two bands of rich drab-gray, with a slight creamy cast, separat- 

 ing the very dark seal-brown ground color into three longitudinal 

 stripes. Belly and sides creamy white, irregularly dotted and 

 blotched with seal-brown. Head pure drab-gray, with markings of 

 seal-brown above, uniform whitish below. 



This snake had the curious habit, often shown by Charina, of 

 coiling itself into a compact mass or ball when disturbed. 



5. On the Type Specimen of Crotalus oregofius. — In the collection 

 of the Philadelphia Academy of Natural Sciences is a jar which 

 bears two labels, as follows : 



Crotalus oregonus Holb., N. Amer. LLerp., Vol. iii, PL 3. Mr. 

 Nut tall. Type. Oregon. 



Crotalus oregonus Holb. 840. Type. T. Nuttall. Oregon. 



This jar contains a young rattlesnake which agrees with the origi- 

 nal description of Crotalus oregonus in ail respects except in length 

 and the absence of rattles. The total length is only fourteen and 

 one-eighth inches. I see no reason to doubt that this is the type of 

 Crotalus oregonus. 



This specimen exhibits all the characters of the species long 

 known under the name Crotalus lucifer. The light postocular 

 stripe is more than two scales wide and the dark streak below it 

 begins below the middle of the eye. The snake now almost uni- 

 versally known as Crotalus lucifer must, therefore, in the future be 

 called Crotalus oregonus Holbrook.
