the abdomen ; broadly conical. Rostrum somewhat rounded at the tip. 

 Rostral hairs inserted far back, finely pectinated, rather long. Lamellae low^ 

 rough, slightly curved, irregular ridges without cusps ; they are short, con- 

 siderably less than half the length o£ the cephalothorax ; they are about twice 

 as far apart at the base, next the abdomen, as at their anterior ends, from 

 which the lamellar hairs arise. These hairs are stout and long, passing the 

 tip of the rostrum by about half their length ; they are strongly pectinated, 

 or spinulated. Inter-lamellar hairs similar, but a trifle longer. Pseudo- 

 stigmata small, and placed partly under the edge of the abdomen. Pseudo- 

 stigmatic organs with rather long peduncles and small pyriform heads ; they 

 stand forward and upward. 



Legs of about average length for the genus ; the first pair pass the tip of 

 the rostrum by about the length of the tibia and tarsus, the fourth pair pass 

 the posterior margin by that of the tarsus only. The tibise are the longest 

 joints, and in the first pair of legs have a small projection in the centre of 

 the anterior margin, which projection bears the tactile hair. The femora, 

 genuals, and tibise each carry a pair of stout, curved, spinulated hairs, and 

 the coxae of the third and fourth legs one similar hair. The tarsi bear several 

 very caducent, finely pectinated or plumose hairs. The claws are tridactyle,. 

 and strong, the central claw of the three is the shortest but the thickest. 



Abdomen about a tenth longer than its width, it is not round in effect but 

 is somewdiat diminished in width anteriorly, the sides there sloping in an 

 almost straight line, and there is a tendency to a median anterior point. 

 There are not any markings on the notogaster, but it bears a large number of 

 extremely large, conspicuously spinulated hairs ; these hairs constitute the 

 great feature of the species ; they are the most striking and remarkable 

 hairs that are found on any Notaspis that I am acquainted with ; some of 

 them are as long as, and look longer than, the whole body of the creature, 

 and the spinulation makes them look even thicker and stronger than they are. 

 The spinules of these, and the other spinulated hairs on the Acarid, are placed 

 at regular intervals and are not jointed to the principal rhachis of the hair but 

 are prolongations of it ; they are placed in alternate pairs, first a pair opposite 

 each other springing from the sides of the rhachis, then a similar pair springing 

 from the upper and under surfaces of the rhachis, and so on alternately. Each 

 spinule points toward the tip of the hair and a little outward (PL 18. figs. 8- 

 10); just the tip of the hair is without spinules (PI. 18. fig. 9). There aro 

 about 60 of these spinulated hairs on the notogaster ; four are arranged in a 

 transverse curved row near the cephalothorax ; seven, of which one is central, 

 in a similar row a little further back ; then two rows of eight each ; and 

 there are several, less regularly placed, on the posterior part of the notogaster; 

 the remainder are round the periphery. 



Ventral surface without markings ; the epimera are smaU and do not nearly 

 reach the median line, those of the second pair of legs are the longest ; thero
