ciation Reports for 1845, and in the Proceedings of the Zoological 

 Society for March 1840 ; these will raise the numher of species in- 

 cluded in the genus to nine. M. Dum^ril gives the following synopsis 

 of the species known to him : — 



I M\\r,t\^,\ router angle of the ventral fins rounded 1. N. brasiliensis, 0{f. 



eiiipiicai ^ ^^ ^^ pointed 2. N. Timlei, Btuch. 



C lateral margins f eyes smaller than the spiracula 3. N. indica, Henle. 



pentagonaH very unequal i eyes equal to the spiracula 4. N. maculata, n.s. (Java). 



I lateral margins nearly equal 5. N. microphthalma, n. s. 



(India). 



, )• caudal fin elongated and narrow 6. N. nigra, n. s. (Brazil). 



nearly circular ^ ^_ rounded 7. N. macrura, n. s. (Indian 



I. ocean). 



Genus 3. Hypnos, n. g. 



Disc elongated, a little emarginate at the middle of its anterior 

 margin ; spiracula veiy close to the eyes, bordered with a crown of 

 numerous long teeth ; no cartilages to the lips ; mouth large, semi- 

 lunar, not protractile ; teeth pointed, not passing the margin of the 

 jaws, of which they occupy the whole length, and to which they are 

 parallel ; bridle of the nasal valve attached to the anterior margin of 

 the upper lip ; tail very short, only passing the posterior margin of 

 the ventral fin by the length of the caudal, which is very small ; 

 two dorsal fins, first smaller than the second. 



This genus contains but one species, which M. Dumeril describes 

 and figures (pi. 12) under the name of H. subnigrum. It is from 

 Australia. 



Genus 4. Astrape, Miill. and Henle. 



Of this genus M. Dumeril enumerates only two species — A. capen- 

 sis, derived as implied by its name from the Cape of Good Hope — 

 and A. dipterygia, Cantor, from the Straits of Malacca. 



Genus 5. Temera, Gray. 



This genus includes but one species — T. Hardwickii, Gray. 

 M. Dumeril closes his memoir with a note upon the fossil Torpedo 

 {T. gigunted) found in the Monte-Bolca, near Verona. 



V. Descriptions of new species of Lepidoptera belonging to the 

 Museum of Paris, by M. H. Lucas (second and third decades, IV. 

 pp. 189-198, and VI. pp. 290-300). 



These descriptions, like those pre^aously published by the same 

 author, are unaccompanied by any diagnoses. The species are as fol- 

 lows : — in No. 4, — 



1 . Papilio Phronius. Resembles P. Proteus. From Cayenne. 



2. Papilio Zeuxis. A little smaller than P. Proteus, to which it 

 is allied. From Venezuela. 



3. Papilio Bochus. Confounded by Cramer and Godart with P. 

 j^neas of Linnaeus ; it is larger than that species and comes near 

 P. Vertumnus and Proteus. From Cayenne. 



4. Papilio Orbignyanus. Allied to P. Proteus. From the envi- 

 rons of Corrientes. 



5. Papilio Gayi. Allied to P. uEneas. From the environs of 

 Cusco.
