San Julidn (near sea level), 10°36’ N., 66°51’ W., Venezuela. On the warm, 
arid northern coast of Venezuela about 7 miles east of La Guaira. The 
hamlet, consisting of a few scattered huts, is located in an irrigated valley 
above the village of Caraballeda. The mountains behind San Julian are well 
forested (Robinson and Lyon). 
San Pedro, Rio*, Bolivar, Colombia. A tributary of the Norosf entering on the 
left below the village of Norosi at the foot of the Central Andes. Collecting 
was done from the site Pefias de Navarro, altitude 178 meters. Region 
humid and heavily forested. 
San Sebastidnf (1,909 meters), 10°37’ N., 73°34’ W., Magdalena, Colombia. 
A picturesque Indian village in the fertile basin of the Rio San Sebastidn 
(Fundacién) on the southern slope of the Sierra Nevada de Santa Marta. 
The surroundings are grass lands cut out of the original lower Temperate 
Zone forests. The land rises abruptly to the north, is extremely rocky, and 
continues through the péramos to the snow-capped peaks. The land to the 
south is hilly and grassy. The valley of the San Sebastidn drops gradually 
westward, passing through beautiful humid forests. To the east there is 
a trail which leads through a pass and continues down the eastern slope of 
the mountain mass through a somewhat drier forest before ending in the 
semiarid valley of the Rio Cesar (Brown). 
Santa Martat, Colombia. Many old records given as ‘Santa Marta’ do not 
necessarily refer to the town or to the ‘‘Santa Marta district” as now under- 
stood. During the period when present-day Colombia was known as New 
Granada, Santa Marta represented the western half of what is today the 
Department of Magdalena. It included the area east of the Rio Magdalena 
from the Santa Marta Mountains south to the mouth of the Cesar. The 
eastern portion of the present department was, and still is, known as Valle- 
dupar. Specimens labeled ‘‘Santa Marta” by collectors who antedated 
Simon, Smith, and Brown are more likely to have been taken anywhere on 
the right bank of the Magdalena from its mouth to the confluence with the 
Rio Cesar. Early specimens from the left side of the Magdalena may have 
been labeled ‘‘Cartagena,’’ and correctly so, as the present departments of 
Atldntico and Bolivar were so known in the New Granadine period. 
“Santa Marta Mountains,’ Magdalena, Colombia. Specimens so labeled by 
Brown were taken anywhere from near Santa Marta, at sea level, to several 
thousand feet higher on the western slope of the Sierra Nevada de Santa 
Marta. See Bonda. 
Sierra Negra*, Magdalena, Colombia. The so-called ‘‘Black Mountains” or 
western range of the Sierra de Perij4 overlooking the town of Villanueva in 
the semiarid Cesar Valley. The well-drained slopes of the range from 1,000 
to 1,500 meters above sea level are given over almost entirely to coffee 
plantations. Higher up, to the summits, 1,500-3,000 meters, and eastward 
in Venezuela, virgin rain forests prevail; lowe: down, on the western slope, 
the country is semiarid with a mixture of grassand scrub. Collecting station, 
Pajalito, in the Sierra Negra was situated almost due east above Villanueva 
al an altitude of 1,265 meters. 
Tarra, Rio* (200 meters, approximately), 8°36’ N., 73°1’ W., Norte de aaa 
Giclestaim A tributary of the upper Rfo Catatumbo, on the eastern slope 
of the Sierra de Perij4, and not to be confused with the much larger Rio Tarra 
of the lower Catatumbo in Venezuela. The author’s collecting station was 
in the deep, broad, humid tropical valley of the Tarra in an abandoned road 
camp of the Colombian Petroleum Company. The region is almost con- 
tinuously rainy except for a definite dry season from mid-December through 
March. It is densely covered with virgin forests and inhabited by a small 
population of the primitive Motil6én Indians.
