Sharpe ; ^Egotheles rufescens, Salvad. ; JE. plumifer, Ramsay ; 

 Micropsalis kalinowskii, Berlep. ; Caprimulgus Rosenbergi, Hartert ; 

 0. nigriscapularis, Rchw. ; C. celebensis, Grant ; C. aldabrensis, 

 Bidgw. : C. Donaldsoni, Sharpe ; Collocalia Wliiteheadi, Grant ; 

 Cypseloides Cherriei, Bidgw.; Apus Willsi (Hart.); A. Shelleyi 

 (Salvad.) ; but of these JEgotheles plumifer and Apus Shelleyi were 

 referred to in footnotes in that Catalogue. Besides which the 

 following thirteen subspecies are also added : Nyctibius jamai- 

 efwws. ari&eus (Gm.) ; Nvctidromus albicollis derbyanus, Gould ; 

 Chordeiles virginicus aserriensis, Cherrie ; Phalcenoptilus Nuttalli 

 nitiduf, Brewst. ; Caprimulgus macrurus ambiguus, Hart. ; Capri- 

 mulgus macrurus nipalensis, Hart. ; Caprimulgus europceus meridi- 

 onalis, Hart. ; Macropteryx mystacea Woodfordiana, Hart. ; M. comata 

 major^'B.&Tt. ; Collocalia fuciphaga unicolor, Jerd. ; Chcetura zonaris 

 pallidifrons, Hart.; Apus affinis galilejensis (Antin.) ; and Apus 

 affinis Kcenigi (Rchw.). One new genus is given, viz. Nannochor- 

 deiles, Hartert [type N. pusilhis (Gould)], and the following altera- 

 tions and emendations are made : JEgotheles Lorice (Cat. B. Brit. 

 Mus. xvi. p. 650) is omitted ; Eurostopus is corrected (p. 23) 

 to Eurostopodus ; Macropsalis forcipata (p. 27) to M. creagra (Bp.) ; 

 the genus Cosmetornis is suppressed and included (p. 30) in Macro- 

 dipteryae, and M. macrodipterus is corrected to M. longipennis 

 (Shaw) ; Heliothreptus is altered (p. 31) to Elioihreptus ; Capri- 

 mulgus lentiginosus stands (p. 55) now as C. trimaculatus (Sw.), 

 Caprimulgus jotalca as Caprimulgus indicus jotaka, and Caprimulgus 

 Kelaarti as Caprimulgus indicus typicus ; Collocalia merguiensis a's 

 C. francica germani (Oust.); Tachornis batassiensis is altered to 

 T. batasiensis ; and the generic name for the true Swifts is altered 

 from Micropus to Apus, but should, we think, stand as Cypselus. 

 Sixteen woodcuts of heads, feet, and tails are given, all of which 

 will be found useful, and the entire work is well got up and con- 

 scientiously executed : and we congratulate Mr. Hartert on having 

 completed so concise and useful a manual of these families.

On the Malpighian Tubes of Orthoptera. 



By M. L. BOEDAS *. 



THE Malpighian vessels in Orthoptera present a close analogy with 

 those of Hymenoptera so far as their number and length is con- 

 cerned, but they differ essentially in their arrangement and mode of 

 opening. They are, as a rule, capillary tubes, more or less elon- 

 gated, cylindrical, tortuous, and arranged in several bundles which 

 open in the majority of species on the summit of six little conical 

 tubercles, arising in evaginations of the anterior extremity of the 

 terminal portion of the intestine. In Porficulidae, Phasmidaa, and 

 Gryllidse the relations of these glands to the intestine are entirely 

 different. 



From the histological point of view these glands consist of an 

 external very delicate peritoneal coat and an internal epithelium
