in the form and disposition of the papillae as well as in the character 
of the nephridial tubercle on the fourth and fifth legs. There are 30 
pairs of legs, a common number for this species. In color, however, 
the specimen before me seems to differ somewhat from the normal color 
of amthurma for according to Professor Pearse’s field notes, it evidently 
showed in life lozenge-shaped markings. Bouvier has found in cer- 
tain individuals indications of lozenges in addition to the median 
dark line, however, so that this variation is perhaps of not very great 
importance. The specimen was fixed in Gilson’s fluid and it is impos- 
sible at present to see any indications of the original color-pattern. 
The present record greatly extends the range of amthurma, but after 
a long series of comparisons I am convinced that it is either a non- 
typical or varietal form of imthurmz. The single female is from the 
Cincinnati Coffee Plantation, altitude about 3,000 ft., 18 miles south 
of Santa Marta, Colombia. 
Field Notes and Observations. By A. S. PEARSE. All specimens 
are from the Cincinnati Coffee plantation, 18 miles south of Santa 
Marta, Colombia. The field numbers are those referred to in the 
preceding taxonomic account. 
49. One Peripatus, in a log 30 X 14 ft. on a hillside southeast of the 
Plantation. Altitude about 3,000 feet. July 7, 1913. 
50. Two Peripatus, same as 49 per locality and date, in a small 
stump 13 ft. high and 5 inches in diameter, with borers (Passalus, 
etc.) imagoes, larvae, and pupae. | 
58. Peripatus in a rotten log with one beetle, isopods, ants, ete. 
Altitude about 5,300 feet. July 8, 19138. 
This log, like the others I had examined up to this time which 
contained Peripatus, was on an open hillside exposed to the sun, 
with Pteris growing all around. I found a cricket in this log 
which was fastened by its dorsal surface by a sticky secretion. 
92. Peripatus on the trail toward Minca below the Plantation. 
Under bark on a live tree about 33 feet above the ground in a 
rather dry, dense forest. Altitude about 2,300 feet. July 19, | 
1913. | 
151. Small Peripatus in the forest southwest of the Plantation, under 
leaves. Altitude about 2,200 feet. Died before being preserved { 
July 21, 1913. 
152. Peripatus in the centre of a very soft log which could be torn) 
| 
apart with the hands. Same locality and date as 151. | 
171. Two small Peripatus beside the trail under the bark of a rather 
firm log which had been bored by beetles. The bodies of these
