Homola orientalis, n. sp. (PL II. fig. 1). 



Cliaracters. — Carapace submembranous, somewhat flattened, the length al)out one- 

 third greater than the breadth, the sides parallel and the regions not well marked. 

 Frontal region deflexed, the rostrum terminating in two subacute spines which are 

 directed forwards. Gastric area slightly convex, armed with nine rounded tubercular 

 processes arranged after the manner of the spines in Homola barbala (Herbst), and some- 

 what hollowed out mesially, the shallow groove thus formed continued on to the rostral 

 process. Hepatic area armed with two l)lunt spines as in Homola barbata, and of these 

 the larger and more external marks the commencement of the lateral border of the cara- 

 pace, the second is situated in a line between the former and the outer gastric tubercle. 

 A line continued along the outer border of the carapace passes between the two hepatic 

 spines, so that the antero-lateral sj^ine is perhaps more correctly referred to the sul^hepatic 

 region of the carapace. The antero-lateral border presents a slight concavity ; it is 

 marked by a prominent spine over the basal portion of the ocular peduncle, and external 

 to this a rounded groove into which the ocular peduncle fits. This border ends in two 

 or three insignificant tubercles in front of the subhepatic region. The lateral border is 

 armed in front by the prominent spine already alluded to, posterior to this are two 

 subacute tubercular spines of no great size, and a series of minute rounded tubercles 

 continued almost to the jjosterior end. The posterior border is slightly raised, and has a 

 mesial curve directed forwards, the first abdominal segment fitting into a well-marked 

 depression. The cervical groove is ill-defined ; it passes to the margin of the carapace 

 between the first two spines of the lateral border, and there becomes lost, its position 

 being marked on the surface of the carapace by an oblique elevation which runs in towards 

 the cardiac area. 



The ocular peduncles are remarkably long, the basal portion slender and cylindrical, 

 the terminal part slightly constricted near the middle, and bearing a dilated cornea. The 

 basal joint of the antennular peduncle is short and of irregular shape, the second joint is 

 considerably longer than the terminal one ; the flagella are of small size. The antennal 

 peduncle is about equal in length to the eye-stalk, and composed of four joints, the first 

 of which has a well-marked auditory tubercle, the second is armed superiorly with a spine 

 which projects over the next joint, the penultimate is long and cylindrical, and about three 

 times the length of the terminal one ; the flagellum is about twice the length of the 

 carapace. The epistome bears a well-marked blunt spine, from which a ridge is 

 continued to the under surface of the rostrum. The subhepatic region is di^dded into 

 two parts by a groove which is directed obliquely forwards ; a few small tubercles are 

 present on the posterior division, while the anterior possesses many short and stout sub- 

 acute spines ; several minute tubercles are present also on the pterygostomial area. The 

 external maxillipedes bear a close resemblance to those of Homola bar^bata as figured by
