Although these records of ticks from Chiriqui represent 
only seven species, probably only a small part of the total 
number present, they include two species which do not seem 
to have been recognized in Panama previously. 
Ixodes ricinus (Linnaeus). A number of males and fe- 
males were collected from a forest deer, Mazama sartorii 
reperticia Goldman, killed near Camp Pital. 
Dermacentor nitens Neumann. Several specimens of this 
tick were taken from a horse at Progreso by Dr. Clark. 
Since this species is commonly found on horses in many 
parts of Panama it is undoubtedly abundant throughout 
Chiriqui. 
Amblyomma cajennense (Fabricius). One of the native 
hunters found an unengorged female of this species crawl- 
ing about on him soon after his return from a trip in the 
forest near Camp Pital. Several specimens were also col- 
lected from a horse at Progreso by Dr. Clark. It is proba- 
ble that this species is as ubiquitous in Chiriqui as in other 
parts of Panama. 
Amblyomma coelebs Neumann. A dead female of this 
species was found in the bag in which a spectacled owl, Pul- 
satrix perspicillata (Latham), had been placed a short time 
previously at Camp Pital. The tick was quite dry and it is 
possible that it may have been carried on the feathers of 
the bird from some nest or dead host. Two females were 
also taken from a horse at Progreso by Dr. Clark. One of 
these, partly engorged, was more than 11 mm. in length. 
This appears to be the first record of this species in Panama. 
Amblyomma mantiquirense Aragao. A number of males, 
females and engorged nymphs were collected from a collared 
peccary, Pecari angulatus crusnigrum (Bangs), that was 
killed near Camp La Vaca. This seems to be the first oc- 
casion on which this species has been found in Panama. 
Amblyomma oblong oguttatum Koch. This species was 
found to be present in abundance upon a collared peccary, 
Pecari angulatus crusnigrum (Bangs), that was killed near 
Camp La Vaca. Numerous males, females and nymphs were
