culmine elevato, arcuato. Macula parva nuda pone oculos, nulla 

 sub eis. 



$ Long. 17 poll. Ala circa 270 mill., tarsus 51, cauda 170, 

 (J ultra alas); rostrum e fauce 59, altit. 23, cum cranio 98. Totus 

 niger, dorso, scapulis tectricibusque violaceo-nitentibus. Rostrum 

 fere coracis, sed magis compressum et longius extensum ; forma ex- 

 acte ut prions ; setae narium non ad medium rostrum extensae, cul* 

 minis basin haud tegentes. Remex 2 a brevior quam 6 a , longior quam 

 7 a . Crederem liunc esse C. encam quae autem aWagler, quoad formas, 

 cum C. frugilego comparatur ; dimensiones etiam omnes C. encce 

 majores. 



This species is less common than the last ; I never saw it in 

 flocks, but only solitary, or paired in spring. The note consists 

 of a tolerably clear, rough krah, krah, which is much hoarser and 

 shorter than in our crow, and more like the rook's voice. The 

 food consists of insects ; in the stomach were found only larvae 

 and butterflies. I never saw this species near corpses, which 

 however are to be obtained everywhere. This is the species which 

 the Europeans in Bengal call Raven. The Bengalese name is 

 Kaak or Dohm Kaak. 



39. Hirundo rustica, Linn. — Some individuals were seen 

 March 23, near Sucsagor, some miles N. of Calcutta. I could 

 easily have shot the first which offered, for it sat on a post at 

 some yards distance, where I was once resting ; but my surprise 

 at meeting here with the Swallow, which in my own country I 

 had cherished with especial affection from childhood, prevented 

 the shot. I am however fully satisfied that this specimen was 

 altogether like those which occur with us ; the white spots on the 

 tail, the white under-parts, red throat, surrounded with black, 

 &c. were seen clearly and recognised instantly. I never saw this 

 bird in other places. 



Obs. Another species of Swallow with a slightly forked tail 

 was also seen near Sucsagor, but not obtained. Probably several 

 species are found in the country, as I thought I saw considerable 

 variety among the Swallows which flew about, though they do 

 not occur so commonly as the two following Cypseli.
