Genus 3 NEOPHYLLOPHORUS nov. nom. 

 New name for Phyllophorus zacae Deichmann and related species. 



KEY TO THE SPECIES OF NEOPHYLLOPHORUS 



Tables with oral disk, with smooth edge and four squarish holes and four smaller wedge-shaped ones. Spire with two 

 pillars and few teeth 1. Neophyllophorus deslichadus (Deichmann) 



Tables with oval to rectangular disk with four large holes and four smaller ones. Spire sometimes reduced to two knobs 



2. Neophyllophorus Iritus (Sluiter) 



1 Neophyllophorus destic 



FIO. 68: 14-16 



Phyllophorus deslichadus Deichmann, 1930, p. 146, pi. 

 18, fig. 3; 1938, p. 135, pi. 1, figs. 15-18; 1941, p. 135 

 (passim); H. L. Clark, 1933, p. 112. 



Diagnosis. — Up to 6 to 7 cm. long, in preserved 

 condition, with 15 to 20 tentacles, of different 

 size, in two indistinctly separated circles. Color 

 brownish purplish. Spicules tables with delicate, 

 oval disk with four large, squarish holes and four 

 smaller wedge-shaped ones; spire two-pillared, 

 with 8 to 12 spines on top. Type: Museum of 

 Comparative Zoology. Type localitj^: Tortugas. 

 Distribution: Known from Tortugas and Bis- 

 cayne Bay, Florida, collected at low tide. Both 

 the Tortugas and Bisca>Tie Bay specimens were 

 collected by H. L. Clark who dug them out from 

 eelgrass roots in firm mud. 



A closely related form is known from the 

 Panamic region (Deichmann, 1941). 



2 Neophyllophorus tritus (Sluiter) 



Thyone trila Sluiter 1910, p. 339, text figs. E, a-e. 

 Phyllophorus Irilus Deichmann, 1930, p. 147, pi. 18, 

 figs. 4-8; H. L. Clark, 1933, p. 113. 



Diagnosis. — Few cm. long in preserved condi- 

 tion; tentacles 18, probably 20 in mature speci- 

 mens. Color grayish violet to deep purplish. 

 Spicules tables with four large holes and four 

 smaller ones in the oval to rectangular disk; spire 

 with two pillars, sometimes reduced to knobs. 

 Type: Possibly in Germany. Type locality: 

 Bird Key Reef, Tortugas, Florida. Distribution : 

 Taken at Tortugas, Florida, and Antigua, BritisJi 

 West Indies. The small size may indicate that 

 the species is based on immature individuals. It 

 may be that it is the young of destichadus in which 

 the spicules are less characteristic and for some 



reason have been partly resorbed, something I 

 have never seen in typical specimens in which the 

 edge of the tables always is firm and even. 



Genus 4 LIPOTRAPEZA H. L. Clark, 1938 



Genus established for Phyllophorus vestitiens 

 Joshua, and two other Pacific forms; the latter 

 have, however, proven to belong in other genera. 

 For the present one West Indian species has been 

 included. 



Lipotrapeza seguroensis (Deichmann) 



FIG. 68; 6-11 



Phyllophorus seguroensis Deichmann, 1930, p. 141, pi. 

 17, figs. 10-13. 



Eulhyonidium seguroensis Deichmann, 1938c, p. 132, 

 figs. 9-14 (with field note by H. L. Clark). 



Diagnosis. — Small forms 5 to 6 cm. in preserved 

 condition, with flexible, soft skin, though rough to 

 the touch. Feet scattered over entire body; 

 tentacles 20 in two circles with five large pairs 

 and five small inner pairs. Color mottled brown. 

 Calcareous ring short, tubular, with insignificant 

 posterior prolongations. Spicules numerous reg- 

 ular tables with four central holes and about 12 

 marginal ones; margin undulated to blunt den- 

 tate. Spire with four pillars and a number of 

 spines on the top. Feet with end plate but no 

 supporting rods. Introvert with tables and ro- 

 settes; tentacles with small perforated rods and 

 rosettes in the distal part. Type: Museum of 

 Comparative Zoology. Type locality: Porto 

 Se^ro, Brazil. Distribution: Known from 

 Brazil, Jamaica, and Tortugas and Cape Florida 

 in Florida. Taken near low tide mark. Near 

 Cape Florida H. L. Clark dug it out of sandy 

 mud in grassy flats. It may very likely be found 

 widespread in suitable localities m the southern 

 part of the Gulf.
