WEST INDIAN CENTIPEDES — CRABILL 191 



fluid or, following thorough dehydration in alcohol, in Canada balsam. 

 Treatment with KOH or NaOH is apt to distort the position and shape 

 of the calyx and of course will destroy the fleshy gland. 



Note D: Heretofore our only source of knowledge of Taeniolinum 

 was Pocock's superficial and in some ways misleading original descrip- 

 tion (1893, pp. 471-472). The following brief diagnoses are based 

 upon the recent examination of one of the two original cotypes, for 

 whose loan I am indebted to G. Owen Evans of the British Museum 

 of Natural History. 



Taeniolinum Pocock 



Generic diagnosis: Antennae not clavate nor geniculate; neither 

 are they conspicuously attenuate. Labral teeth well developed and 

 numerous; labinim weakly arched. First maxillary telopodite lappets 

 long and robust; coxostemal lappets evidently absent. Second 

 maxillary claw bipectinate. Prostemal sclerotic lines not apparent, 

 i.e. not passing to or toward the prehensorial condyles. Tergites not 

 sulcate. Each sternite from one through the penultimate bears a 

 distinct pore field; no pore field raised or divided; pore fields of an- 

 terior third of body distinctly and transversely elliptical. Each 

 coxopleuron has two essentially round and concealed pores ; each pore 

 is associated with a homogenous gland. Each ifltimate leg is swollen 

 and strongly, evenly attenuate distally; ultimate tarsus consisting of 

 two articles; pretarsus is distinct and tuberculate. 



Taeniolinum setosum Pocock 



Species diagnosis: Male cotype, British West Indies, St. Vincent 

 Island, collected at 3,000 ft. in moss on a mountain by H. H. Smith. 

 Total length about 13 mm.; with 49 pairs of legs. Antennae neither 

 clavate nor geniculate; distal half very weakly attenuate (the whole 

 structure strongly contracted); articles 6-14 densely setose; each 

 article but the 14th much broader than long. Cephahc plate slightly 

 longer than wide; sides weakly rounded; rear margin straight and 

 very slightly overlapped by succeeding plate. Clypeus without a 

 typical clypeal area, in its position a subcircular field of minute pores; 

 paraclypeal sutures pronounced; transbuccal sutures very vague; 

 posterior margin straight, deeply pigmented and well sclerotized. 

 Labrmn very \vide and weakly arched, nearly straight; the entire 

 posterior margin with about 32 prominent, strong but pale teeth. 

 Mandible with the undivided dentate lamella evidently having 6 

 strong, widely separated teeth. First maxfllae without medial divi- 

 sion; medial lobes long and triangular, lappets of coxosternum ap- 

 parently absent; each telopodite indistinctly separated from coxo- 

 sternum and indistinctly biarticulate, with a robust lappet equahng
