coast of Africa through the Indie and Pacific to the West coast of 

 tropical America (California, Mexico) and to Japan and Australia. 

 Remark. Of this species, which is often confounded with 

 the preceding one, larger specimens are better represented 

 in collections from our region than of F. villosa Klunz. One 

 gets the impression, that, when young, both are living in the 

 shore water, where F. petimba Lac. grows to a large size, and 

 is easily captured, while F. villosa Klunz., when growing larger, 

 lives outside the shore water and seems therefore to be rarer. 



2. Fam. MACRORHAMPHOSIDAE. 



Physoclists. Body oblong or elevated, compressed. Head 

 produced into a long tube formed by the prolonged bones of 

 the mandibulary suspensorium and the anterior prolongation 

 of the praeoperculum. The other opercular bones are well 

 developed. Of the true mouthparts the intermaxillaries are weak, 

 the maxillaries fairly broad, the mandibles well developed, all

to show the larger scutes and the crests on the head, while the scales are 

 ommitted. Dorsal armour: i, 2, 3 upper dorsal row of plates; I v, lower 

 lateral row. Ventral armour: I VI row of unpaired keeled scutes, above 



them the paired scutes. (After JUNGERSEN). 



the bones are without teeth as also vomer, palatines and 

 pterygoids. The parietals are wanting. No lateral line; lateral 

 line canals on head present. Head and body all over covered 

 by small, rough scales, formed by a scaly plate in the epidermis, 

 with the hindborder more or less toothed and with one or 

 more keels on its surface. Each scale is connected by a stalk 

 with a bony plate imbedded in the cutis. Besides the trunk 

 is armoured with large bony plates, which make it stiff and 

 immoveable and which are partly hidden by the scales (see Fig. 6).
