with six disposed in a ring about it. The pseudorostral lobes are 

 juxtajDOsed but for a very short distance in front of the ocuhir lobe. 

 The telson (fig. 36, c) is longer than the penultimate somite of 

 the abdomen but not so long as the last two somites taken together. 

 Distally there are three or four spines on the lateral margin; 

 apically there are three spines, of which the median is much longer 

 than either of the lateral ones. Below, and somewhat external to 

 the two lateral spines, there are two other long, practically bristlelike 

 spines. 



FIGDEH 36. — Hemilamprops californica, new species, female with brood poucli : a, Lateral 

 view, X 19 ; &, anterior end of body from above, X 19 ; c, posterior end, X 33 ; d, distal 

 end of second pereiopod, X 33. (Magnifications approximate.) 



The first pereiopod was lacking in all the specimens at hand. The 

 second pereiopod (fig. 36, d) is moderately long. The length of its 

 three distal joints is approximately as 19 : 14 : 12. 



The peduncle of the uropods (fig. 36, c) extends very slightly be- 

 yond the telson. The endopod is about as long as the peduncle. The 

 exopod shorter. Of the three joints of the endopod, the first is 

 somewhat longer than the other two taken together; the terminal 

 joint is somewhat shorter than the penultimate. On the inner mar- 

 gin of the peduncle and of the endopod there is a relatively dense 

 armature of spines; on the inner margin of the exopod setae, on 

 the outer margin spines. 



Length. — One specimen has a length of about 8 mm. The other 

 two are smaller, about 6 and 5.5 mm long, respectively.
