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 imthurmi 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 imthurmi, but after 

 a long series of comparisons I am con\dnced that it is either a hon- 

 typical or varietal form of imthurmi. 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 I2 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 1^ 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, etc. 

 Altitude about 5,300 feet. July 8, 1913. 



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 3^ feet above the ground in a 

 rather dry, dense forest. Altitude about 2,300 feet. July 15, 

 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
