longa, hot hunas. This is a rather common form of trepang 

 throughout the Archipelago. It is black, and the skin is smooth, 

 without teats or prickles. It is more pointed and oval than the 

 oh nyeow sam, which it most nearly resembles. The length of 

 the dried adult is from 5 to 11 centimeters. It is found in com- 

 paratively shallow water near the shore on a sandy bottom. 

 In Manila this species is quoted as being the most desirable of 

 all the trepang; the price paid, however, will scarcely bear this 

 out. The large size is valued at 45 pesos per picul; medium, 

 30 pesos per picul ; small, 18 pesos per picul. 



Che sam (Plate IV, fig. 7) . — Great prickle trepang, moi what 

 che, hot ista. This trepang closely resembles the buoy hwoh sam,' 

 but is considerably larger. It is uniform black when dry, and 

 with the exception of the belly it is entirely covered with long 

 prickles. This is a common form and is found in shallow water 

 near reefs, usually on a sandy bottom. The adults, when dry, 

 are from 6 to 19 centimeters long. In life this species is more 

 or less pink. Its maximum length is about 46 centimeters. It 

 is distinguished by the long prickles, which cover the back and 

 sides and are frequently joined at the base, forming starlike 

 rosettes with from three to five points. Only the most ex- 

 perienced traders can disting-uish between this form and the 

 expensive buoy huah sam ; therefore trepang with the long black 

 prickles is usually classed as che sam, the value of which is as 

 follows : Large, 45 pesos per picul ; medium, 30 pesos per picul ; 

 small, 20 pesos per picul. 



Ang thoot sam (Plate IV, fig. 6). — Smooth red trepang, hot 

 bantatvan. This is a small, very smooth dull red trepang. It is 

 from 3 to 10 centimeters long. It is very common in shallow 

 water and commands the following prices: Large, 30 pesos per 

 picul ; medium, 20 pesos per picul ; small, 15 pesos per picul. 



Peh thoot sam (Plate IV, fig. 18). — White trepang. While 

 this form is of little value, it is important because of its abun- 

 dance. It lives in shallow water and is gathered by men wading 

 along the reef. It is from 3 to 9 centimeters long and uniform 

 white when dry. Its value is from 7 to 18 pesos per picul. 



Twa bing thoot sam (Plate IV, fig. 15). — Brown and white 

 trepang. This trepang is found in very shallow water along the 

 reef. It is of medium size — from 3 to 11 centimeters long — and 

 is valued at from 10 to 20 pesos per picul. 



Bing thoot sam (Plate IV, fig. 16). — Red and white trepang. 

 This small trepang is rather smooth with a slight trace of red; 

 its length is from 2 to 9 centimeters. It is found in shallow 

 water. Its value is from 7 to 14 pesos per picul.
