Lysiosquilla sp?

This lysioerichthus larval form is represent- 
ed by a single specimen taken in a plankton 
tow in the Molokai Channel. Its very large 
size (45 mm.) immediately draws attention. 
All structures are the same as for the previ- 
ously described larvae of this genus. It was 
temporarily believed to belong to L. maculata, 
but its size and relative immaturity (cf. Fig. 
25^, which is only 15 mm. long) seem to 
indicate that it may be the larval stage of a 
species of Lysiosquilla which has not been 
found in the adult form in Hawaii. 
Lysiosquilla maculata

Figure 25^ represents one of seven lysio- 
erichthus larvae, three of which were collected 
in plankton tows at Truk Island and four 
from Kawaihae, Hawaii. These are fully de- 
veloped larvae, which I believe to be the last 
larval stage of L. maculata. This conclusion 
is based on an examination of postlarval forms 
and the adults of this species. Appendages, 
except raptorial claw, telson, and uropods, 
resemble those of adult L. maculata; facies 
of postlarval telson show through chitin, very 
closely resembling telson of postlarval forms 
shown in Figure 25/. It is very probable from 
these facts that the next molt would produce 
the postlarval stage of L. maculata. Specimens 
range from 15 to 16 mm. from the tip of the 
rostral spine to the posterior margin of the 
telson. 
The postlarval form (Fig. 25/) undoubtedly 
belongs to L. maculata. All anterior append- 
ages are the same as those of the adult, and 
the raptorial dactylus bears nine teeth on its 
inner margin similar to the condition found 
in some of the adults of this species. The 
telson and uropods have the same general 
appearance of the adult as well. These spec- 
imens and the adults have eight spines along 
the outer margin of the exopod of the uro- 
of last larval stage of coroniderichthus larva; h, dorsal

pods. A single specimen measuring 16.5 mm. 
in length was collected at Kawaihae, Hawaii, 
at a night light station, which further sub- 
stantiates the identification because the adult 
species is very common in that region.

In Figure 2Ga there is represented the last 
larval stage (coroniderichthus) of some un- 
known species of Coronida. This form is 
found in the Ala Wai Canal, Oahu, and at 
Kawaihae, Hawaii, in moderate numbers dur-
