LYSIANASSIDAE 61 



Uropods 1-3 extending back about equally, the inner ramus in each slightly shorter 

 than outer ramus. 



Colour (as preserved) pale yellowish, with a greyish transverse band on each segment 

 from peraeon segment 1 to pleon segment 5, extending on peraeon segments 1-5 only 

 to the upper parts of the side-plates ; eyes black. 



Remarks. The resemblances of this form to umbo as regards the mouth-parts and 

 1st gnathopod appear to outweigh the absence of features usually found in the members 

 of this genus, such as dorsal processes and the produced apex of the 1st joint of the 1st 

 antenna. The feebly indurated integument may possibly be due to the specimens having 

 been taken from a fish stomach, though they are in excellent condition and not at all 

 mutilated or semi-digested. In longicorne there is a very similar segmental arrangement 

 of pigment.

From the nearly related genera Lepidepecreum, Lepidepecreopsis , and the new genus 

 described below, this genus is distinguished by the entire telson.The 4th side-plate is 

 received into a definite groove on the 5th side-plate, as in Waldeckia. 



Lepidepecreella ovalis, n.sp. (Fig. 23). 



Occurrence: 1. St. 42. South Georgia. 1 $ 8 mm. 



2. St. 45. South Georgia. 2 $$ 6-5 and 7 mm. Types. 



3. St. 140. South Georgia. 2 $$ 7 and 8-5 mm. 



4. St. WS 33. South Georgia. 1 $ 7 mm., 1 $ with embryos 8 mm. 



Description. Very close to ctenophora, Schell., but distinguished as follows : postero- 

 inferior angle of pleon segment 3 with a tiny 

 upturned acute point followed by a small 

 and feeble semicircular notch (both features 

 obscure in nos. 3 and 4) ; margin above very 

 minutely and feebly serrulate ; telson longer 

 than broad, ovate; uropod 3 with outer 

 ramus half as long as peduncle, inner mar- 

 gin minutely serrulate, 2nd joint minute, .

inner ramus completely fused with pe- b _ TeIson . ,. Uropod 3, with apex of ramus further 

 duncle; rostral process more prominent, enlarged, 

 extending as far as apex of epistomal pro- 

 jection; tooth on posterior margin of pleon segment 4 higher and more strongly 

 developed. Integument indurated, strongly and closely punctured, especially on pleon 

 segments 1-3.
