TURCKHEIMIA. AT 
Turckheimia nodosa, sp. n. 
Adult female, length 34 lines. . 
Cephalothorax black, shining, and glossy ; caput abruptly elevated, the summit rather flat; thorax rather higher 
at the beginning of the posterior slope than at its junction with the caput. Thoracic indentation rather 
deep and transverse, a whitish longitudinal central line running from this indentation backwards. 
The eyes of the central four form a quadrangular figure, whose posterior side is much less in length than its 
anterior side. 
The legs are dull reddish-orange, with black and pale yellowish annuli; palpi black, with a yellow annulus at 
the base of the radial joint. 
Falces black. 
Maville and labium deep black-brown, tipped with a pale hue. 
Sternum heart-shaped, black, with a central longitudinal yellow-ochreous stripe on its posterior half. 
Abdomen large, of a somewhat quadrate form, with its fore corners rounded off; upper surface flattish convex, 
with four very large divergent corner-gibbosities which are enlarged and round at the extremities, of a 
blue-blackish metallic hue, clothed with short yellowish and other hairs and pubescence. At the posterior 
extremity between the two hinder gibbosities are two others much smaller, of a nipple form, and in the 
median longitudinal line, the anterior one being slightly the longest. These last, as well as the whole upper 
surface, hinder slope, and sides of the abdomen, are of a dull reddish-orange-yellow, marked with a bold 
pattern of oval and other forms, of a deep blackish-yellow-brown colour, and of a velvety appearance, the 
various markings margined with a line of bright yellowish-white hairs. The colours and markings are 
apparently caused by dense pubescence. The underside is black, marked on each side with two or three 
transverse scribbly lines of white hairs. The genital process is very small and inconspicuous, and of a 
dull whitish-leaden hue. Spinners black-brown. 
Hab. GuatemMaa, Chicoyoito (Turckheim). 
Weare indebted to Mr. Sarg for an example of this exceedingly interesting spider; it was 
found by Herr von Turckheim in its small geometric snare on a citron-tree at Chicoyoito. 
Turckheimia walckenaérii, sp. n. 
Adult female, length 23 lines. 
The cephalothorax has the caput considerably raised, and the sides of the thorax gibbous, the indentations 
between these two parts (caput and thorax) being very strong, and at the thoracic junction isa deep 
transverse somewhat curved pit or indentation. The colour is deep brown, paler on the front and sides 
of the caput, and clothed, but not densely, with coarse whitish or grey hairs, 
The eyes are small, in the usual three groups. The four central eyes describe a square whose anterior side is 
longer than the posterior, and its eyes are placed close to the fore margin of the clypeus. 
The falces are not very long, but strong, inclined backwards and of a deep brown hue. 
The legs are rather short, moderately strong, clothed with coarse grey and other hairs, and a very few fine 
spines, relative length 1, 2, 4,3, or1,4, 2,3. They are of a yellow colour, the fore half of the femora of the 
first and second pairs is deep blackish-bistre-brown, the other legs and joints annulated with deep brown. 
The palpi resemble the legs in colour and armature. 
The maxille and labium are deep brown tipped with dull yellowish. 
The sternum is black, with eight dull orange spots or eminences round the edge, corresponding with the in- 
sertions of the legs. The posterior spot is geminated, forming one only for the two posterior legs. 
The abdomen is large, somewhat quadrate, and has a small subconical eminence on each side towards the 
anterior extremity, and four others forming a group, two in the median line and one on each side at the 
posterior extremity, which extends considerably over the spinners, and is somewhat caudiform ; the 
distance from the spinners to the eminences being equal to the whole length of the abdomen. The colour 
above and on the sides is pale yellowish-brown, marked with black markings and whitish spots and lines 
(owing to the shrinking of the epidermis in spirit of wine but little regular pattern can be seen, except- 
ing a large curvilinear diamond-shaped marking indicated by white lines, just in front, in the middle, of
