Page 292, No. 7, Cernfopsyllus pyrrhtdce. Dale. — " On bull-finches." The 

 single specimen of this species must, like the preceding one, be referred to 

 Ceratopht/Uu.i (/allinulce. The name is consequently a synonym. 



Page 292, No. 9, Cerafopst/Utix citrine/lfp, Dale. — " In yellowhammer's ne.sts." 

 The three specimens of tliis specries are, like the preceding two, referable to 

 Ceratophyllus gaUinuhi'. 



Page 292, No. 10, CeratopstiJlus pratenxi.t. Dale. — " In meadowpipit's nests." 

 This name likewise is a synonym, the two specimens being identical with Cernfn- 

 phi/llufi gnllinulfB. 



Page 292. No. 11, CeratopayUux a(rlcapinfP,T>H\e.- — "In blackcaji's nests." 

 The single species, a female, is identical with Ceratophi/IIns ffallinula. 



Page 292, No. 12, Cerrrfopxy/Iiis ciiicrere, Dale. — " In whitethroat's nests." 

 This species is again a composite one, and the name innst consequently be rejected. 

 Two of the males and the three females are identical witli Peratophi/J/us gaJliuu/ce, 

 while the third male is indistinguishable from Cera/ophi/Unx gaUirKf. 



Page 292, No. 13, Ceratopxiillux arvensix, Dale. — " In skylark's nests." The 

 type of this species has unfortunately been lost. 



Page 292, No. 14, Ceratopst/Uus trochlli. Dale. — '' In willow-wren's nests." 

 The type of this species has also been lost. 



Page 292, No. 15, Cerafopstjllns caudati, Dale. — "In long-tailed-tit's nests." 

 TJiere are two females of this species which is identical witli CeratophyUux qaUunilce. 



Page 292, No. If5, Cerafopsi/llux xpini. Dale. — " Taken by my father off a 

 siskin, February 9th, 18fi3." The single female specimen of tliis species is identical 

 with CeratopxyUux qaUlnce. 



Page 292, No. 17, Ceratopxylltix eenas, Dale. — " In stock-dove's nests." The 

 two specimens of this species are indentical with Ceratopht/UHx qnlliiKE. 



Page 293, Ceratopxifllus palumbi. Dale. — " In wood-pigeon's nests." There are 

 two male specimens of this species. The one is an undoubted example of 

 Ceratophyllus sciurorum, while the other represents a new and obviously un- 

 recognised form. The name palumbi, belonging as it does to a composite species, 

 and in consequence the new species shoulil be redescribed. 



In the Daleian collection there are two specimens received by Mr. J. C. Dale, 

 from Mr. Curtis, of Curtis's own species ('eratophyllus eloiigalus. These specimens 

 are identical with the insect referred to as Cnvi'x&'s, elonyatushy the author. (Novit. 

 Zoolog., vol. V, p. 542, 1898). 



From these facts it will be noted that the Daleian collection contains four 

 types of British Siphonaplera. These four species are well known at the present 

 time, but the alteration of some of the names becomes necessary. Ptilex cuuiculi 

 is the correct name for the species now known as Vulex goniocephalus. Ceratophyllus 

 muxtehe remains the same, altliougli the author has to be changed from Wagner to 

 Dale. Ceralophyllux gaUinulce will henceforth be the recognised name for 

 Ceratophyllus Neirxteadi ; while TyjihlopsyUa sorecis will have to replace Typhlop- 

 sy/ld uracil is.
