 gus (jabot) The intestine proper is only a foecal reservoir. The 

 urinary or Malpighian tubes sometimes secrete calculi. No bile 

 has been found in the secretions of these tubes. A point of great 

 importance is touched upon by the author, namely : the passage 

 of the chyle from the stomach to the blood. It is well known 

 that there are in Articulates no lacteals as in Vertebrates to effect 

 this process. Plateau states that the . products of digestion pass 

 through the walls of the digestive canal by an osmotic action and 

 directly mingle with the blood. 



Horny Crest on the Mandible of the Female White Peli- 

 can as well as the Male.— In all the standard works on the 

 Birds of North America, it is stated that the horny crest or 

 " button " on the upper mandible of the white pelican (Pelecamis 

 erythrorhynchus) is exclusively a male appendage. I dissected, 

 April 20th, 1875, an adult female of this species whose ovaries

The Western Nonpareil in Michigan.— On the 15th day of 

 May last, Dr. H. A. Atkins of Locke, Ingham Co., Mich., shot 



I have mounted and have now in my collection, Baird, Brewer, 

 and liidgway's "North American Birds" contains the following 

 note on this species: "This beautiful species has only doubtful 

 claims to a place in our fauna. It is a Mexican species and may 

 occasionally cross into our territory. It was met with at Boquillo, 

 in the Mexican state of New Leon by Lieutenant Couch. It was 



given by Bonaparte as from Peru. It is also found at Cape St. 

 Lucas, where it is not rare, and where it breeds." 



It was shot in the vicinity of some Indigo birds, C. cyanea, on 

 the first day of their appearance in this locality. — J. M. B. Sill,
