allowed us to examine. As we possess the species here described from Central Asia, 
the Fiji Islands, from various parts of Africa (West, South, and East), and from the 
Malagasic subregion, we are probably right in applying the name gallinaceus to this 
insect.

6. Echidnophaga ambulans 
Ech'ulnophaga ambulans Olliff, Proc. Linn. Soc. N. S. Wales (2). I. p. 172 (1886) (N. S.Wales, on Echidna 
hystrix) ■ Baker, Proc. U.S. Nat. Mus. XXVII. p. 431, 439 (1904); id., I.e. XXIX. p. 124 
(1905). 
Sarcopsylla myrmecobit Waterhouse, Proc. Ent. Soc. Land. p. 23 (1887) (nom. nud., West Australia, oft 
Myrmecobius). 
Olliff's description of ambulans is as follows : — 
' Broadly ovate, castaneous, shining, with indistinct green reflections. Antennae 
capitate, finely setose. Eyes rather prominent, small, pale castaneous. Head 
moderately convex above, finely and indistinctly crenulate in front. Thorax short. 
Abdomen ovate, rather strongly convex above, somewhat truncate posteriorly; the 
anal region armed with a few strong bristles. Legs pale castaneous, tips of femora 
and tibiae darker ; tibiae with two feeble notches on the external margins. Length, 
2 mm. ; greatest width, 1^ mm.' 
From this very general description it is impossible to decide which of the 
Australian Sarcopsyllidae is the insect from which the description was taken. As 
Olliff had numerous specimens — apparently all — we applied to the Australian 
Museum for the loan of a specimen, but were informed that our request could not 
be complied with, the type of ambulans being unique. 
We have two species of Sarcopsyllids to which the generic and specific 
descriptions of Echidnophaga ambulans apply equally well. We accept the name
