of the palpus is long enougli to turn one and a half times around the

Lophocarenum longitubus, new. 



Plate XIII, figure 6. 



Length, r5""", Cephalothorax yellow-brown. Legs yellow. Ab- 

 domen dark gray. The hump is rounded and does not extend far 

 back on the head. The hind middle eyes are on the front of the 

 hump. Each side of the hump is a horizontal groove, in the middle 

 of which are the holes in the head. The tibia of the pali)iis has tw^o 

 prominent black teeth. The tarsus is irregularly shaped and trun- 

 cated at the outer end. The tube is long and stiff", and bends around 

 the flat end of the tarsus.

Lophocarenum rostratum, new. 



Plate XIY, figure 1. 



Length, 2"'"'. Color light brownish yellow on the cephalothorax and 

 legs, and gray on the abdomen. It varies in different individuals, 

 some having the abdomen almost black and the other parts proportion- 

 ally dark. The hum)) of the male extends forward beyond the front of 

 the head. Fig. \a. The hind middle eyes are on the top of the hump 

 near the middle. The holes are in oval grooves just back of the side 

 eyes. The tibia of the male palpus has a long and slender hook 

 as long as the tarsus. The tube of the palpal organ passes round it 

 once, and is supported at the end by a stout spine. The female is 

 much like the male, but has no trace of the hump on the head.

Lophocarenum scopuliferum, new. 



Plate XIV, figure 2. 



This is a small dull-colored species, i-5'""' long. The head is ele- 

 vated about as much as in spinifera, and the holes are in grooves 

 above the side eyes. The male palpi have the tibia as large as the 

 tarsus, which it partly covers. On its outer side is a row of long stiff 

 hairs curved forward toward the end of the joint. The palpal organ 

 is simple, all the parts being very small and short. The female has 

 the head slightly elevated at the back part, and is about the same 

 size and color as the male.
