Fig. 25. Larval forms of Lysiosquilla. a, Antizoea; b, lateral aspect of lysioerichthus larva and first abdominal'^ 
appendage; c, dorsal aspect of last abdominal somite, telson, and uropods of same; d, ventral aspect of lysioerich- 
thus larva; e, ventral aspect of last larval stage of L. maculata; dorsal aspect of first postlarval stage of L. maculata. 
inner longer than outer; carapace nearly as 
broad as long from base of anterolateral spines 
to base of posterolateral spines, lateral mar- 
gins turned downward and toward median 
line; most preserved specimens with abdomen 
and telson reflexed anteriorly so that ventral 
opening of carapace is completely closed. 
Specimens measure 14.5 to 28.5 mm. in 
length. The 28.5 mm. specimen shows the 
facies of ten spines along the inner margin of 
the raptorial dactylus much the same as those 
seen in the adults of L. maculata.
