582 MR. 0. SALVIN ON NEW BIRDS FROM Costa RICA. [Nov. 8, 
A well-marked and distinct species, combining characters of both 
groups of this genus. 
7. EMBERNAGRA SUPERCILIOSA, Sp. U. 
E. supra olivaceo-cinerascens, capite cinereo: striis longis per 
oculos et pilei lateribus a rostro ad nucham transeuntibus ob- 
secure brunneis, distinctis: subtus cinerascenti-albida, pectore et 
corporis lateribus saturatioribus: campterio flavissimo, rostro 
superiore fusco, inferiore albido, pedibus pallide fuseis. 
Long. tota 5, alee 2°35, caudee 2, tarsi ‘9, rostri a rictu °55. 
Hab. Costa Rica (Nicoya). 
E. chloronote, Salv. (P. Z. 8. 1861, p. 202), et affinibus suis simi- 
lis, sed capitis striis conspicuis et statura minore distinguenda. 
In Dr. Sclater’s and my paper on the ‘ Birds of Panama,’ P. Z.S. 
1864, p. 352, reference will be found to the distinctions between the 
Central American and New Granadian forms of this genus, viz. 
E. chloronota, Salv., E. striaticeps, Lafr., E. conirostris, Bp. The 
pectoral band is hardly shown in the present bird, which, with the 
paler colour of the occipital and superciliary stripes, renders it recog- 
nizable from any of the above primo visu. 
8. MyRMECIZA LEZMOSTICTA, Sp. n. 
M. badia : capite toto et corpore subtus a gula ad medium ventrem 
nigricanti-plumbeis, hoc dilutiore : mento et gula nigris, albo 
vittatis ; alarum tectricibus minoribus et campteriis nigris, api- 
cibus albo terminatis, tectricibus reliquis ferrugineo terminatis : 
plumis interscapularibus in parte basali albis, media nigris, 
macula tota badio celata: rostro nigro, mandibula inferiore me- 
dialiter cornea, pedibus obscure fuscis. 
Long. tota 5°25, alee 2°5, caudze 1°8, tarsi 1°05, rostri a rictu *85. 
Hab. Costa Rica (Tucurrique). 
9. GRALLARIA DIVES, sp. n. 
G. supra pileo et dorso cinereis, plumis omnibus nigro marginatis : 
uropygio obscure olivaceo : remigibus extus rufis: gula et ventre 
medio albis : loris pallide ochraceis : pectore, corporis lateribus, 
erisso et tectricibus subalaribus saturate fulvis, pectoris plumis 
nigro marginatis: ungue postico longo et gracili : rostri man- 
dibula superiore brunnea ; inferiore albida, apice brunnea : pe- 
dibus pallide fuscis. 
Long. tota 5:5, alee 3-1, caudee 1°4, tarsi 1°5, rostri a rictu 1. 
Hab. Costa Rica (Tucurrique). 
Affinis G. fulviventri, Scl. (P. Z. 8. 1858, p. 282), et G. macularia, 
Temm. (Scl. /. c.); sed ab illa remigibus extus rufis et ungue postico 
rectiore, ab hac regione oculari vestita non nudiuscula et ungue postico 
longiore et rectiore differt. 
This species appears to have the hind claw straighter and weaker 
than is usual in Gral/aria. In general coloration it is closely allied 
to the above.
