CEPHALOPODS OF THE PHILIPPINE ISLANDS 89 



Type. — U.S. National Museum. 



Type Locality. — Off Port Maricaban, southern Luzon. 



DiscussiOM. — This is the third species of small Doryteuthis to be 

 recorded; it has much in common with Adam's (1954) two species 

 from the Indo-Malayan region, D. sibogae and pickfordae (emended 

 from pickfordi). This species may easily be distinguished from the 

 others by the hectocotylization of both ventral arms and the elonga- 

 tion of the left and by the smooth terminal ventral arm tips. 



Distribution. — Known only from Port Maricaban, southern 

 Luzon, and Varadero Bay, northern Mindoro, Philippines.

Description. — The mantle is long, slender, and cylindrical and 

 tapers gradually to a long attenuated taillike point, which is very 

 long and slender in the male but less so in the female. Dorsally the 

 mantle margin is produced in a distal lobe in the midline but ventraUy 

 it is emarginated beneath the funnel with sharp pointed lappets 

 beneath each eye. In the male a prominent raised ridge on the ventral 

 surface of the mantle in the midline extends from the anterior margin 

 to the tip of the tail. The ventral surface of the female is smooth. 



The fins are short and slender if they are not considered to extend 

 to the tip of the tail, but they are long and slender if the ridge, slight 

 as it may be, running from the fins to the tip is considered to be a 

 connecting ridge between the two fins. This latter view has been 

 taken here. The anterior edge is nearly straight, only slightly convex, 

 the posterior border concave, the fins at about the midpoint tapering 

 to a low indistinct ridge. 



The funnel is small and compact, reaching to about the level of 

 the pupil of the eye, and deeply set into the head. The funnel organ 

 is an inverted V with oval ventral pads. The valve is large, semi- 

 circular, and just within the aperture. 



The head is small and compact with large eyes covered by the outer 

 skin of the head and with a minute pore anterior and ventral to the 

 eye. There are two small lappets forming the olfactory crest at each 

 corner of the funnel excavation, the inner lappet about half the size 

 of the outer one.
