MALLOPHAGA. 237 



utilla (Vieill.), sanderling, Culidris leucophaea (Pallas), pectoral sand- 

 piper, Pisobia maciilatd (Meill.), knot, Tringa canutus (L.), turnstone 

 Arenaria interpres (L.), and is also recorded from the red-breasted 

 nut hatch, Sitta canadensis (L.). Of course this last record from the 

 Passeres is simply a case of straggling. This nuthatch was the only 

 bird taken on August 25 other than semipalmated plover, sanderling, 

 and yellowlegs. One of these Liraicolae was certainly the host of the 

 single specimen of N. complexivus found on the nuthatch. Kellogg 

 and Chapman describe it from Calidris leucophaea (Pallas) and Pisobm 

 minutilla (Vieill.). It combines several characters presented as diag- 

 nostic of older species, whence its name. 



Nirmus actophilus Kellogg and Chapman. — Two females from the 

 sanderling, Calidris leucophaea (Pallas). It is common on this host, 

 Kellogg reporting it on nine out of fifteen birds. It is well marked 

 and easily recognized from the other species of Nirmus common on the 

 Limicolae. 



Nirmus parallelus Osborn.^ — A single female of this species was taken 

 on the greater yellowlegs, Totanus melanoleucuh (Gmel.). The species 

 was described by Osborn from Oxyechus vociferus (L.). Its general 

 form is much like that of Lipeurus baculus, the body being very long 

 and slender, the abdomen parallel-sided, and the legs like the Lipeuri; 

 but the antennae are alike in both sexes, and it is a Nirfnus. Among 

 the Nirmi it most nearly resembles A^. boephilus Kell., and Osborn re- 

 marks: ''Kellogg's description of A'', boephilus from a female specimen 

 from the same host agrees quite closely in most respects, but differs 

 in the proportions of the head. The types for my description being 

 now in the Boston Society of Natural History, a detailed comparison 

 is impossible. Comparisons of a greater series of specimens will very 

 likely prove their identity, in which case Kellogg's name will have 

 priority." On this point Mr. Carriker says: "I have examined the 

 type (Osborn's) of A^. parallelus and compared it with specimens in my 

 own collection which I have identified as A'', boephilus and find that the 

 two are quite distinct." 



Nirmus boephilus Kellogg. — A single female of this parasite was 

 found on the semipalmated plover, Aegialitis semipahnata (Bonap.). 

 Kellogg described it from a female taken on the killdeer, Oxyechus 

 vociferus (L.). It is a long slender species with parallel sides, and a 

 distinct brown marginal band on head, thorax, and abdomen. 



Nirmus candidus Nitzsch. — Four specimens, male and female, from 

 the flicker, Colaptes auratus luteus (Bangs.), are undoubtedly this form. 

 Mr. Carriker's notes regarding these are as follows: "These specimens 

 agree almost exactly with Giebel's description of the species (Insecta 

 Epizoa, p. 149), but without a good plate and a more detailed de-
