Coloration. The general appearance of the spider when viewed with naked 

 eye is such as if he had a black abdomen and a yellow cephalothorax and legs. 

 On closer examination under microscope one notices that the coloration of the 

 abdomen is complex. Curved interrupted black lines the only ones shown on 

 fig. I so as not to obscure the drawing, are on a general field of purplish spots 

 and dots with small yellow spaces separating them. The spinnerets are light 

 yellow. The legs are yellow including coxae. Sternum is dark owing to irreg- 

 ular pigmentation. Lip and maxillary plates are lighter than the sternum, yet 

 show pigmentation. Palpi, especially their tibia mottled with black. Bulb 

 yellow. Chelicera yellow with some black pigmentation in front. Cephalo- 

 thorax yellow with a narrow black margin, very regular black lines and spots 

 as shown in figs. 2 and 9, black area around the eyes, and small black dots 

 and short lines all over the surface. 



The only specimen in existence was caught by Mrs. Petrunkevitch 

 on June 26, 1907, in our home at Short Hills, New Jersey, where we 

 lived at the time. When I came to study it in 1910, Emerton's paper 

 was already published. Since his specimen which he identified as the 

 male of Orchestina saltitans had evidently no resemblance to my 

 specimen, I reluctantly placed my specimen as O. saltahunda. Is it 

 after all the male of O. saltitans? The description given by Banks of 

 the single female which he collected is not sufficient to clear the mat- 

 ter. There is a certain similarity both in structure and coloration be- 

 tween his female and my male, but also not inconsiderable differences, 

 as may be seen from a comparison of the two descriptions. It were 

 perhaps safer to give my male a new name, but I am not anxious to 

 increase the number of names. It is strange however that all our 

 knowledge of Oonopid spiders in the United States is based on four 

 specimens only. So far as I know, no other specimens have been col- 

 lected. In the case of Gaii:aso)iwrpIia it is very likely that the species 

 really occurs in Florida. But is it sure that the other specimens be- 

 long to the fauna of the United States and have not been accidentally 

 imported with fruit or some other goods from the West Indies or 

 Central or South America ?
